TITM Kinetics of coke formation on the alumino-silicate catalyst
used when cracking petroleum fractions and hydrocarbuns

TEM In order to study the kinetics of coke formation during the
cracking of the kerosene - gas oil fraction (200 - 320'C), the Golovanov-
Panchenkov method is used, in which the catalyst is in contact with live
vapours from the raw materials during the whole course of the experiment.
The aependen,.e of the amount of coke formed, on the cracking period, was
studied for the case of the kerosene - gas oil fraction (200 - 320 0C) of
Komsomol'sk petroleum, hexadecane and decalin. To understand the kinetics
and the mechanism of coke formation it is important to know how the coke
is precipitated on to the surface of the catalyst. The percentage coating
of the catalyst by the coke can be calculated for a monomolecular layer.

PERIODICALt Kinetika i katalizt 1960, Vol. 1, No. 2, pp. 188 - 196
TEXT: The authors attempted to derive a kinetic equation for the
cracking of hydrocarbong. Proceeding from the radical chain reaction
A ---)' 11A1+ 2A2+ .'.. VnAn (a) (A initial substance, A i reaction
products, V stoichiometrio'coefficients) they write: W 1 - k[Rj [Aj (2)
(WI reaction rate, [R],[A] concentration of radicals and initial sub.-
stance) and W . k rAj + k r-'[Al (3). This equation takes into account
I 1L-j 2 V-j
the possible effect of two processes on the reaction rateg a) decomposi-
tion of the initial molecules into free radicals; b) reaction between
free radicals and initial molecules. Furthermore, the rate W 2 is derived
for the formation of free radicals. The following is assumed: 1) The

radicals are formed by collision or by a monomolecular decomposition of
the initial molecules; 2) the free radicals are consumed by reaction with
the initial molecules. The Lnteraction among the free radicals is
negligibly small due to their low concentration. The authors writet
W = k [Aj 2+ kl(A] - kL, r" (4). Taking account of the

they obtain: (k /k )[A] + k /k (5)~ By substituting (c.) in (2) or

k3' = k2k3/(kIk4+ k2kj) if (5) was substituted in (3). At low pressure.,
the collision among the initial molecules does not essentially con.-
tribute to the formation of radicals, and equation (6) will be of first
order. The following relation is written for thermal cracking in con-
tinuous flow and gaseous state, the results of R-bf.3 being taken into

TEXT: The authors report on their tests concerning polymerization of
propylene on a molybdenum oxide and a mixed nickel oxide molybdenum
catalyst, respectively. It was ascertained that neither pure aluminum
oxide nor a molybdenum oxide catalyst on an aluminum oxide carrier effects
a polymerization of propylene, so that mixed catalysts, i.e., with addition
of nickel, cobalt, copper oxides~ etc. are widely used. Relevant tests made
by the authors at 140 - 2000C showed that the optimum conditions for a
polymerization of propylene on a mixed nickel oxide molybdenum catalyst
onlan aluminum oxide carrier under atmospheric pressure are a temperature
of 1600C and a moderate (15-20 h-1) rate of gas supply. These test results
are graphically shown in Figs. 1, 2, and 3. An increase of teirperature and
supply rate results in a decrease of the yield Of D'Olymerizate fractions.

TEXT: The-authors were able to prepare eymenes in high yields by alkylat-
ing toluene in the gaseous state and under atmospheric pressure in a
stream of propylene, using an industrial aluminum"silicate catalyst. A
special device (Ref. 1) was used for this alkylation. The alaiminum-Bilicate
catalyst had the following composition: 14.01 A12 03f 84.66 SiO 2' 0-36 Na20'
0-13 Fe 0 and 0.60 CaO, and traces of zinc and MgO. The toluene was

chemically pure. Propylene was prepared by dehydratlon of isopropyl alcohol
over aluminum oxide at 380 0C. At 3000C, a molar ratio of toluene.: propylene
of 3 : 1 and an addition rate of 0.45 volumes of toluene per hour with
respect to the catalyst volume, the authors obtained eymenes in 77% yield,

TEXT: -The author notes that Toropovts and Brodskayale interpretation o f
the temperature dependence of A' and 60 in his equation for calculating
the viscosity of fluids is incorrect. He further notes that he has shown
in Ref. 2, that A' depends on temperature, as may be seen from the physi-
cal signifizance of this quantity. Thus, the temperature dependence of A,
requires no further proof. As the author had assumed in Ref. 2 that A'
is constant only within small temperature rangem, Toropov and Brodskaya
found,certain rules in the divergence between calculation and experiment.
It is further pointed out that the assumption of a constant temperature
for A, is wrong when calculating F_ 0 for different temperatures, since

Thermionic Emission Method
PERIODICAL: Zhurnal fizioheskoy khimiij 1960, Vol. 34, No. 97
pp. 2124-2125
TEXT: Mention is made in publications that the method mentioned in
the title may be used for the isotopic analysis of boron, and offers
the fo.7.1oving advantages as compared to other methods: 1) Low material
consumption, 2) no "memory" effect, 3) a small number of peaks left
over due to impurities, and 4) high probability that no secondary
processes act upon the analysis results. For the practical use of the
method mentioned in the title, the ion current, which, according to
published data amounted to jo-13 a, had to be measured acourately by
means of series mase spectrometers.- To solve the problem, the intensity
of the ion current must be increased to 10-12 a, and its siability must
be improved. All measurements were made by means of the mass spectro-
meter MC-4 (MS-4) with a thermionic source. For heating, 20 mm long,

0.8-1.0 mm wide, and 0-05 - 0.1.mm1hick bands were used. Borate, meta-
borate, and a borate-boroxide mixture served as emitters, the first
compound being the most favorable one. The intensity of the ion current
increases with the reducing properties of the band material (Pt, Ni,
W, Ta). From an annealed platinum band, no Na BO+ ions were emitted.
2 2
The ion current emitted from the surface of annealed Ni :J9 W-, and
Ta-bands had an intensity of the order of 6-10 14 - 5 .10 a. There-
fore, the attempt was made to increase the intensi';y of the ion cur-
rent by addition of pulverulent reduction agents (Al, Mg), of which
magnesium was found to be the most effective. When using a mixture
of borate powder as emitter, a sufficiently intensive (of the order
of 10- 11 a), constant ion current was obtained, permitting the analysis
of-boron isotopes with an accuracy of 1%. The optimum vorking tempera-
ture was 700-750 0C. The analysis results are given in Table 1. In cal-
culation, no correction was introduced for the content of heavy oxygen
isotopes, To explain the "memory" effect,analyses of specimens with
highly different isotope compositions were carriel out successively
on one day. The results are given in Table 2. In contrast to the results

TEXT: Alumosilicate catalysts used for the cracking of hydrocarbons have
an acid character. The type of acid and the role of the various acids upon
the cataly-tic process have hitherto not been clarifi-ed. V. A. Chernov
(Ref. 7) showed that in montmorillonite aluminaj besides proton exchange,
also an exchange of aluminum ions is possible, and that alumina can be
regarded as an aluminum salt of alumosilicic acids. The present Dapex deals

conducted with NaCl, LiCl,, and sodium acetate solutions of differsnt con-
centrations. The acidity caused by the exchange of the alkal-A. metal for the
proton in the catalyst was determined by a method of V. A. Chernov (Ref. 8).
The ion exchange was determined by potentiometric titration of the soluticns
(after two days' vigorous shaking with the catalyst). The results obtained
show that the amount of the exchanged protons is much smaller than that of
the aluminum ions. After the exchange reaction, aluminum was detected in
the NaCl and LiCl solutions, while this was not the case with the sodium
acetate solution. This is due to the fact that aluminum acetate hydrolyzes
immediately on the surface of the catalyst where It is aeposited aq aluln:'rjum
hydroxide, an equivalent amount of acetic acid being di-t!solved. Experiment
and calculation show that the maximum amount of the hydrogen and aluminum
ions of the catalyst exchanged by alkali metal ions is 1;ractically independ-
ent of the'type of the latter (i.e., the values for Li and Na ions are
practically equal). Por the above reason, the amount of acetio aoid
forming from the sodium acetate solution during the exchange of the ions
of the catalyst for Na ions corresponds to the sum of the equiLvalents of
the exchanged hydrogen and aluminum ions of the catalyst,, There are

TITLZi A New Method of Separating the Boron Isotopes-r-1
PERIODICAL: Zhurnal fizicheskoy khimii, 1960, Vol. 34, No. 10,
pp. 2370 - 2371
TEXTt A method of separating boron isotopes by a selective extraction
with water and isoamyl alcohol in an apparatus already described (Ref-.-16)
has been developed. After the distribution of boric acid along the cells
of the apparatus the first and last fraction were analyzed for the iso-
topic composition. The analysis was carried out on a MC-4 (MS-4) mass
spectrometer by a method alrcady described (Ref. 17). The results obtained
show that together with the distribution of boric acid between water and
isoamyl alcohol, a fractionation of the boron isotopes takes place, i.e.
in the first fraction a concentration of the light isotope B 10 , and in the
last fraction of the B 11 isotope. Thus, it if; in principle possible to

employ the method of an extraction by liquids for the separation of boron
isotopes. A calculation of the separation coefficient of a single
fractionation yielded a - 1.0027. It is assumed that by a combination of
the complex formation characteristic of boron and an extraction, the
separation coefficient is increased and the method described rendered
more economical. There are 1 table and 18 references: 6 Soviet, 6 US,

between 20 - 6000. After having passed through the column, the complex
is heated to 17500 in the desorber 35 filled with glass pipe pieces and
heated with the oil of thermostat 3~6. The liberated BF is conveyed back
into the column through the reflux condenser 39, and Chorex is collected
in vessel 25'. BF samples are*taken in a complex form through stop cook

(MS-3) mass spectrometer on the bssis of the peaks 10 and 11. The following
results were obtained: In the exchange reaction between BF3 and Chlorex,
an-isotopic separation occurs, B10 concentrating in the liquid phase. The
.separation factor increases from 20 to 6000 when the temperature of the
column rises, and amounts to 1-015tO-OO5 at 6oOc. S.J. Babkov and

TITLE: The Part Played by Chemical Reactions in
Thermionic Emission
PERIODICAL: Doklady Akademii nauk SSSR, ig6o, V-31 131, Nr 2, PP 357 - 359
(USSR)
ABSTRACT: The authors give a report on their experiments concerning the
interaction of an ion-emitter with a Fuetal base acting.as a
heater. The investigations were carried out by means of a mass
spectrometer of the type MS-4. The Ion exchanger A120 3 -4SiO2*XH20,
which was impregnated.with a CsCl solutionp was used as emitter.
Applied to a carefully cleaned platinum base in form of a thin
coating, no ions were emitted by the emitter. Applied onto a
tantalum base, it emitted Cs+-ions. On a platinum basep which
wasq howover, mixed with tantalum powder, the emitter gave the
same ion current as on the tantalum base. The following investi-
gations vrere carried out for the purpose of determining the in-
fluence of the chemics.1 activity exorted by the metal powder
admixed to the enittp,.r up
,pn the ion current. The effect of Cu, W,
Ta, Zr, 11, and j2MpLiiitevWas Investigated. The ion current in-
creased m1th the activity of the metal. Graphite powder yielded

the same emission as tantalum. Also platinum, which wes repeated-
ly exposed to the flame of a gas burner, may cause an ion current,
probably because of the absorption of impurities, chiefly of car-
bon. Farther experiments concerned the emission of Cs* during
heating up to 15000 without addition of metals to the emitterp the
following temperature decrease to 6000 also resulting in an ion
currentp probably as a result of the thermal dissociation of the
emitter by the previous high temperature. Addition of MnO 2 -led to
an initially considerable decrease of the ion currentp which in-
creased, however, again in the further coitrse of the experiment.
From all these results, the authors draw conclusions as to a
chemical interaction between emitter and 7)aeel the formation of
Cs-atoms, and their ionization on the surface. They carry out a
calculation of A Zo and show in figure I that the logarithm of

Deuterated Alcohol
alcohol yields hydrogen with a content of 3.4 per cent of HD, whereas
leopentane formed by hydrogenation contains only 2.3 per cent of mono-
douteroiaopentaneo The authors explain this fact by the different rates
of exchange reactions of C2H5 OD for H2 as well as by olefin hydrogenation
on the surface of the catalyst. Hence'it results that the hydroxyl
hydrogen of the alo*ohol solvent does riot directly partioipate.in the
reaction of hydrogenation. The hydroxyl hydrogen is exchanged for the
hydrogen sorbed on the surface'of the catalyst. If, however, an olefin
is present in the system, it reacts with the sorbed E2 and RD in such a PK
way that it is also sorbed on platinum, Thusp the two possible reactions
of isotopic.exchange between the olefin and hydrogen and the alcohol as
well as the reaction of hydrogenation of the olefin have a limiting
stage in oommong i.eep tba sorption of hydrogen on platinum. If a7l
these processes take place simultaneously, the exchange reactions are
retardedq whereas the exchange of the olefin for alcohol is completely
surpressed. The authors thank L. N. Gorokhov, Z..V. Gryaznovag and I. V.
Gostunakaya for their assistance. There are 2 tables and 17 referencesp

sorption processo the authors used the model of the so-called quasi-
homogeneous grain according to Pshezhetskiy (Ref. 4). Since sorption
proceeds more quickly than diffusion, in each point of the grain an
equilibrium is established between the sorbed substance in the gaseous

TEXT: Since the effective capture cross section of thermal neutrons
amounts to 0.05 barn for B 11 , it may be used in form of zirconium and
yttrJum boride, etc. as heat-resisting material in reactor construction.

2 BF 3 enters the bottom part of column 3, the liquid anisole passing the
pump system 6 enters the absorber 4, where also BP 3 enters after having
passed the column. Here, the complex compound BF 3-aniBole is formed again.
Samples were taken periodically by means of 5. By means of 4, 5, B (Fig.2)
6 1., anisole were filled into the 15 1. glass vessel 1. The electromag-
netic JMtAb(EMIB) agitator 2 was started and then BF 3 introduced. The
water cooling of absorber 26 and coolers 14, 24, 44 was put into operation,
the thermostats 19, 42 connected and the temperature of column 41 and de-
sorber 18 adjusted. The boron complex passed through a rubber bulb and 10
into the siphon preceding the dosing device 12-17. By means of electromag-
net and impulse transmitter a copperplated iron bar fitted in the glass
tube 12 was moved up and down rhythmically as desired (2-12 imp/min). Then
the complex passes the water-cooled elbow 14, the buffer vessel 15 filled
with a glass spiral, and the dropper 16 and enters the desorber 18. The
best results were obtained with the mechanical pulse transmitter with,

flow velocity was 2 ml/min. The electronic pulse transmitter withq AM-26
(DGTs-26) rectifier, Cp2C (SG2S) tube, ~r_M-l (M-1) and P4-90 (RN-90)
relays gave a large-number of pulses (3-30 imp/min) with low consumption
of liquid. The complex was decomposed in the glass-packed desorber 18
(length = 0 cm, interior diameter = 20 mm) which was heated by warm oil
from the 4-24 (TS-24) thermostat 19. BP 3 passed through the return con-
denser 44 into column 41. The anisole contaminated by resin entered the
evaporator 21. It flowed through the inner tiibe and then over the glass
beads, where it was evaporated. The resin was evacuated by 20. 21, 22,
and 23 were it was heated by a nichrome coil, The anisole vapors passed
into-the oolumns 22 and 23 consisting of 3 glass tubes telescoped into
each other. Anisole vapors passed through the inner tube (diameter - 1cm),
the niohrome spiral was wound around the intermediate (diameter - 2 em) ,
the outer (diameter - 4 am) served as heat insulation. The temperature of
the column was regulated by means of a rheostat and controlled with a
Cr-Al thermocouple. knisole for spraying the absorber 26 packed with
glass rings was supplied by the cooler 24. 25 served for evacuating the
CY presumably formed. The complex subject to isotopic exchange in

column 41 was formed in the absorber. The column consisted of a tube
(length - 1.5-2.2 m, diameter - 18 mm) in the outer jacket of which water
coming from the TC-15 (TS-15) thermostat circulated. The inset consisting
of Fenske glass rings etched with HF + NH4F occupied a space Of 3-3-0.6 mm.
The sampling system 27-39 was evacuated through 38 in a prevacuum. Then
26, 32, and 33 were cooled with liquid nitrogen by means of Dewar vessels,
31 and 35 closed. A certain quantity of gas tapped from the column
through 29,25 being closed for this period, was frozen in 36 by means of
a Dewar vessel and further cooled in 32 and 33- 32 and 33 were unsoldered.
The analysis was made by a MC-3 (MS-3) mass spectroscope, the sample ob.-
tained in test 3 was converted to borax and analyzed by means of K-4
(MS-4) according to A., M. Kolchin. In the first test (I) (length of column
= 2.20 m, of absorber - 6 cm) a part of the BF3 was not absorbed by anisole
and escaped~ thus the low coefficient of separationg 1-05. Also in the
second. test (II) (column = 1~5 M; absorber - 50 cm) BF3escaped. Only in
the third test (M) (dimensions as for (II)) BF 3 was absorbed quantita-
tively. A coefficient of separation of 1.42 was attained after 32 hr.

With too high (A) or too low (B) temperatures in the column either complex
formation occurs in the column and sampling is impossible (A) or a part of
BF3 escapes (B). Consequently, the temperature of the column has tD be
such that the complex of given composition is saturated. This was ob-
tained in the following way: the temperature was slowly increased until
BF3 vapors left 25 and then reduced by 2-30C- It was found that the red
color of the anisole complex is due to products of resinification formed
under the influence of atmospheric humidity. The complex is colorless in
the column. The plant may serve for any complexes whatsoever, provided
that the temperatures in desorber and pump system are changed. The
production of B10F3 concentrate requires charging into the top part of
the column. A. M. Kolchin and V. F. Malakhov are thanked for their

khimiij 11, 1933, 1959) that the steady state in the separation of oxygen
isotopes sets in long before the equilibrium ozone concentration is
attained. The concentration turned out to be about equal to that found
as a result-of investigations carried out under different conditions
(different values of the specific energy U/v, different dimensions of
ozonizersq different methods of ozone accumulation and sampling), and
showed to be independent of the concentration of the ozone obtained. The
present work engages in changing the conditions so as to attain the isoto-pe
equilibrium and the concentration coefficient at changed pressure- and
temperature ratios in the system. The investigation was carried out in a

device described in 7-,ef. 1, that is, in a ievactor of 600 mm length
provided with a I mm wide spark gap. The discharge power was determined
from the volt-ampere characteristic with the aid of the equation
U - Vo(Iav - or ) derived by Yu. V. Filippov and Yu. M. Yemellyanov
(Ref. 2: Zh. fiz. khimii, 31, 896, 1957; a, 1042, 1959), where I av is
the mean value of the current flowing through the ozonizer, Ior the mean
value of the current in case of a critical terminal potential in the
ozop,izer, and V0the amplitude value of the ignition voltage discharge.
The effect of pressure was stuO,ied in the range 300 - 900 mm Hg with the
walls of the ozonizer exhibiting a temperature of 200C. The mean concen-
tration coefficient was constant within the test errors, and is computed
from the equation 8mean - 1.100 � 0.013, where 0.013 is the mean errori
in more than 75% of the tests, the mean error was smaller and equal to
0.010. The steady state in the process cf anotopic exchange would be
attained if the values of U/v were close to one whirh corresponds, in our
case, to a duration of the gas in the discharge of 1 - 2 seconds. The

is raised (Fig. 2). Five series of tests were'carried out at a Wall
temperature varying between -19 and +920C and 'constant pressure of 76Q mm
Hg. The results obtained showed that a rise in temperature causes the-
concentrati6n. edeffioient t*0 increase ('Fig. 3). A temperature ride in the
.i-reactor causes a considerable drop of the ozone concentration. Thp data
p-obtained indicate that the separation of oxygen isotopes in the electro-
synthesis of ozone is not determined by the exchange of oxygen isotopes
'but
between oxygen and,synthesized ozone, directly by the formation of
ozone from oxygen. Indicative of this is the independence of the distri-
bution coefficient S on the durstion of oxygen in the discharge zone and-
the relatively high experimental. value of S (about 1.10 at room-temiperature)

The first results obtained for this system are described. The separation
of boron isotopee,was carried out in an installation designed for the pre-
11
paration of the isotope B . Design and mode of operation of this instal-
lation had been described previously (Ref. 5). The only alteration con-
sisted in a more effective attachment made of W1819T (lKhl8U9T) stainless
steel in the form of three-faced 2 by 2 mm spirals of 0.2 mm diameter wire
instead of the glass attachment used previously. Phenetole "p. a." without
additional purification was u.sed. The experiments with the phenetole
complex showed that this complex foams at a slight temperature increase.
Thia.greatly complicated the operation of the siphon through which the
co4lex entered the column. The column temperature during the experiment
was 3000, that of the aesorber AJ17000. The complex was admitted at a rate
OfIVI ml/min. After 14 hr of operation a gas sample for the isotope
analysis was taken from the absorber. Mass spectrometric analyses conducted
by A. M.-Kolchints method using borax ions as emitters (Ref. 6: A. M.
Kolchin, V. F. Malakhov i G. 14. Panchenkov Zh. fiz. khimii, 3A, 2124,
1960) showed that the isotope ratio B11/B16 in the specimen had the value
5.1e + o.13 ( for the reference specimen the ratio was 4.09 � 0.06). This
result corresponds to a total separation coefficient of 1.26. As in

and disilylpropune derivatives is accompanied by a regular increase
in dt. Lengthening the polyethylsiloxane chain by successive di-
ethylsiloxy units is also accompanied by a regular increase in 15t.
In addition, the following pairs of analogoiis compounds were
investigateds diethylsilane-n-pentane, (lipropylsilane-n-heptane,
dibutylailane-n-nonane, phenylmethylailanti-ethylbenzene, and'phenyl-
dimethylailane-iso-propyl'benzone. The aurfaoe tensions of the alkyl-
silanes were close to those of the corresponding hydrocarbons,
while the surface tensions of the alkylarylsilanes were 1.5-2 dyne/cm
higher than those of the corresponding hydrocarbons. There are 5
zables.

TEXT: The refractive indices at 200C for the C and F
lines of hydrogen (for the first time) and for the D line of
sodium have been measured for 46 compounds of the following classes:
the hexaalkyl derivatives of disilylmethane, disilylethane, and
disilylpropane, and of disiloxane, aryltrialkylsilanes, diaryl-
dialkylsilanes, and linear and cyclic polyethoxysilanes. From the
results, the individual, mean and specific dispersions, and the

molecular refraction for the D line, have been calculated. As
a rule, in any one class of alkylarylsilanes those in which the
alkyl group is ethyl have the highest refractive index. The re-
fractive indices of dialkyldiarylailanes are about 0-05 units
higher than those of the aryltrialkylailan(ts with the same alkyl
and aryl groups. In the case of the phenyll;rialkylsilanes, the
introduction of a methyl group into the 4- position of the phenyl
ring and then a second methyl group into the 3- position increases
the refractive index, while the situation is reversed in the case
of the aryltrialkylailanes. The specific dispersions of aryltri-
alkylailanes are 15 - 20 % lower than those of the corresponding
diarjrldialkylailanes. The refractive indices of the hexaalkyl
derivatives of disilylmethane, disilylethane, and disiloxane
increase with a rise in the molecular weight, those of the di-
siloxanes beind leas than those of the corresponding members of
the other classes. On passing from hexamethyldisilylmethane to
the corresponding ethane and propane derivatives, the refractive
index increases by 0.0025 units per CH2 group added, while the
specific dispersion is decreased. The change in the specific

TEXT: The solidification behavior of 31.organosilicon
compounds has been investigated in order to determine their true
melting points and purity, and the oonditions under which glasses
are formed. The compounds were of the following types: hexaalkyl
derivatives of disilylmethane, -ethane, and -propane, and of
disiloxane, phenyl-, 4-methylphenyl-, and 3, 4-dimethylphenyl-
trialkylailanes, diphenyl-, bis-4-methylphenyl-, and bis-3,4-
-dimethylphenyldialkylsilanes, linear and cyclic polyethylsiloxanes,

dialkylsilanes, and an aryldialkyleilane. The main feature of the
apparatus used is that the sample was contained in a double-walled
glass vessel immersed in liquid nitrogen, the rate of cooling being
controlled by the degree of evacuation of the space between the walls.
riany of the compounds underwent pronounced supercooling and others
did not crystallize but formed glasses. Where a glass was not fomed,
the m.p. of the material as such and the true m.p. of its main con-
stituent were determined graphically b~ Rossini's method (J. Res.
Rat. Bureau Standards, 32, 197 (1944) . In the series of phenyl-
trialkylsilanes, the methyl and propyl compounds supercool only
slightly and then crystallize spontaneously, while the ethyl com-
pound crystallizes only after the deeply supercooled liquid is
seeded, and the butyl com-und forms a glass. Somewhat similar
behavior is found with ot..ar series of compounds, the following
also forming glasses on cooling; 3,4-dimethylphenyltripropyl- and
-t-"ibutylsilanes, diphenyldiethyl- and*-dibutylsilanes, bis-4-
me-thylphenyldimethyl- and -dipropylsilanes, bis~3,4-dimethyldiethyl-
silane, hexapropyldisilylmetl_~.ne and.-ethane, and the polyethyl-
siloxanes containing 5, 6, 7 and 8 oxygen atoms. The viscosities
