TEXT# The results obtained by H. S. Davis and collaborators (Refs. 1-3)
lead to tho oonclusion that the absorption rate of olefin in sulfuric
acid in directly proportional to the interface between the liquid and the
gasp the partial pressure of olefin in the gas$ and its physical solubility
in the liquid. The reaction rate in, howevert practically indopsndent of
the intensity of sulfuric acid intermixing, provided the surface layer
is not disturbed. The conclusion is drawn that the reaction prooeeds in a
z
thin surface layer of the acid, in which there appears a steady con-
centration gradient of the reacting components, which determines the ab.
sorption rate of ol*fin. For the reaction in the gas washer the author
derived the definitive kinetic equation

TEXT& To check their previous assumptions regarding the alkaline pro-
tection of the oxidation process (Refs. 294), the authors carried out
experiments on the oxidation of isopropyl benzene in the presence of dif-
ferent alkaline additions (in an equimolecular ratio). Isopropyl benzene,-
was obtained by alkylation with an aluminum chloride catalyst. The method
of these exreriments has been described in Ref. 1. The previous assumptims
concerning the inhibition of the oxidation process of isopropyl benzene
by means of the products of acid decomposition of its hydroperoxide were
confirmed. Addition of alkaline salts of weak organic acids inhibits
the acid decomposition of this hydroperoxide by binding the strong
organic acids formed in th~i oxidation process. Unlike what is seen in the

presence offree alkali lyso the salts of organic acide do not activate
the alkaline decomposition of the hydroporoxide of i;opropyl benzene to
form free radicals. Alkali salts of organic acids accelerate the above
oxidation process, as compared with the process without alkaline addition.
The quantitative acceleration effect depends on the nature of the anion
of the acid, and is nearly inversely proportional to the strength of the
acid. The undesirable impurities in commercial isopropyl benzene do not
inhibit oxidation; the real inhibitors are their acid conversion products.
The inhibitory impurities are strongest in the initial stage of the
oxidation process, when an intensive accumulation of the inhibitory
products taken place. The inhibitory action of undesirable impurities in
commercial isopropyl benzene is identical with the inhibition of the
oxidation process by the by-products tasulting from the acid decomposition
of the hydroperoxide of isopropyl benzene. Diagram 1 shows the oxidation

PMUODICALs Kauchuk I rez1na, no. 2, 1961, 4 - 11
TE(Tt According to available literature data (Table 1) the authors con-
clude that resin acids containing conjugated double bonds have the strongest re-
tardIng effect on the process of what," copolymerization of butadlene with styrene.
Tnese bonds are thought to be the main reason for the disruption in the normal
polymerization proa*sa and, thus, the cause of ordinary colophorty being unsuitable
for technical uce. The main task In modifying colophony is thought to be the re-
moval of the compounds containing the conjugated bonds. The two main chemical
transformations suggested for this purpose are hydration and disproportionation
(see schem). Both pro~_zses are baved on the destruction of the conjugated dou-
ble bonds, either by the addition of hydrogen or an a result of its splitting--off.
The d1sproportionatlon d 'iffers from the hydration In the source of the hydrogen

In the products of reaction. Extensive research was carrIod out In Um Soviet
Unions In order to determine which of the two processes to use for the modifica.-
tion process of colophony and.th* pro~uotion of colophony emulsifiers for the SR
Industry. Hydration work was carrl.*d out at the, Yaroslavl 1 (Ref. 4) and Voroner:h
(Ref. 6) SR Plants and at the VNIISK..Disproportionation was systematically car-
ried out at the VN11SK and at the VNIINeftakhlm. The present article deals with
the main sumary of the&@ wo ,rks id the further methods for perfecting the devel-
oped processes. Several types of nickel catalysts were tested and -the industrial
"nickel on diatomaceous earth7 used In the petroleum industry was found to be the
most active one. Certain relationships betwe*n the pressure of hydrogea and the
rate of its absorption In the hydration of colophony on the above.;.mentioned cata-
lyst were derived which led to the follo" conclusions: 1) The maximum quanti-
ty of th* absorbed hydrogen irfdreas*x with the pressure of the latter asmand to
bey,oonneated with the state or equilibrium. 2) The rate of hydration Increases
proportionately to the hydrogen pressure (Fig. 0. 3) Tbo'stoichiometric differ-
ent~ In the oxperlmeni at pK2 - ta atm between the residual content of the adetic
acids (2.4%) &M the quantity of the absorbed hydrogen (0.42 moles to I mole' of
acid) leads to Uw conclusion that at low pressures of hydrogen, simultaneously
with the hydration an an active cata2yot, tl*.e reactions of disproportionation maj

take place at a sufficiently high rate; 4) The harmful reaction of the splitting-
off of the carboxyl group, the specific gravity of which drops with an increase
In the hydrogen pressure takes place at a sufficiently high rate, simultaneously
with the hydratIon an the nickel catalyst. The consumption of the catalyst dur-
Ing the hydration process me tested on two typos of nickel catalyst, using two
different mothodm of transformation depth control (Pigs. 2, 3). The results seen
I the graphs are explained by the fact that the 1n1t1al oolophony contains cata-
on
lytic wpoisons", which Irreversibly block the active surface of the catalyst and
bring about the deactivation of a certain amowt of the submerged contact, the
value of which depends on the concentration of the "poisons" In the colophony.
Conclusions are drawn from the experimental results that the isomerization reac-
tions of the resin acids with the nickel contact do not catalyze, i.e., they take
place homogeneously (thermally). The average rates of reaction were determined
in order to establish the relationship of the hydration rate to the quantity of
the catalyst from the curves in the experiment with 2, 4 and 8% "Ni-Cum of the
contact (Fig- 3, dotteO lines, and Fig. 4). The relationship was found to be
k - v (3 a), where v In the rate of reaction, k - constant of the rat* of reao-
tion, 8 quantity of the submerged catalyst, % of the colophony weight, a - the
quantity of the Irreversibly poisoned catalyst (for the given case the value am-

plain the Insufficient stability and relatively low production Indices of the ex-
perimental-industrUl. hydration of colophony at the Voronezhakly zhirkombinate
(Voronezh Fat Combine). The authors conclude with rompect'to the hTdrition proc-
ess that In the case of colophony It could be accompanied by reactions of dispro-
portlonation If the applied catalyst hars sufficient activity for this purpose.
In the case of disproportions;tIon, "Ni on diatomaceous earth" proved to be ap-
plicable as catalyst yielding & product of reaction with a sufficiently low con-
tent of abietic acids. Comparisons were made of the colophonles obtained during
the process of low-tempstrature wqxFule copolymerizatlon of butadiene with styrene
according to a trilon-rongalits formulation at the VNIISK. Obtained e 'iL showed
that 'in the first approximation both methods give satisfactory emulsifiers to the
saw degree. The initial non-modiflod colophony in unsuitable for the polymeri-
zation process. The quantity of nickel catalyst was found to have the same ef-
fact on the d1sproportionation process of colophony as on the hydration process,
i.e., at low-quantiiies of the agntact the rate of roaction In very low. Tbere

'be accomplished by a thermodynamic shift to the left of the state of equilibrium:

id. The large batches VNIISK-produced of disproportionated colophony on "Ni on

ever, the disproportionation process on the nickel catalysts was considered un-
practical for industrial use, since this catalyst speeds up, in addition to the
main reaction, the non-desirable splittlng-off of the carbonic acid with a loes
of 10% and more of rosin acids. Palladium was tested in this connection to be
used as a catalyst. Conclusions were drawn here that palladium in subjected to
poisoning by the "poisons" present in the colophony during the process. The ap-
plication of the palladium catalyst was found to decrease the raw material losses
due to practid,iLl removal of this decarpoxylation reactions and is cheaper as a cab-
alyst. Experiments at the VNIISK showed that the specific activity of a unit

obstacle for th4 commercial use of this process was the gradual poisoning
of the catalyst. The reactors of the model set-up (capacity 1 and 10 1)
were hollow tubes. In testing the nickel catalyst the first laboratory
tests showed the possibility of achieving a continuous process over a
period of 500 hours at 225-2300C. The first experiments on the affect
of the palladium quantity in the catalyst showed that the duration of the

regenerating catalyst action depends largely on the quantity of the
palladium. When using a catalyst made of palladium applied on granulated
large-porous aotivated 6AY-3 (BAU) carbon (2.3%) favorable process
indexes were maintained. It was concluded that the duration of the oata-
lyst activity increases when the initial colophony is purified of any
catalytic "Poisons". The effectiveness of the action of the palladium
catalyst depends on the size of its grains. Recuperated aotivatedhi>-3
(AR) carbon was used as the carrier instead of BAU-3. The relationship
between the depth of transformation of abiatic acid to the rate of the
colophony supply and temperature was established in order to determine
the kinetic laws of the disproportionation process (Fig. 6). The thermal
effect of the process was also investigated:. Experimental data showed
that in all cases the temperature inside the catalyst was higher than in
the aluminum block of the reactorp i.e. during the entire time of the
catalyst action within the t4mperature range from 200 to 25000V the process
remained exothermic. In selecting a technology and apparatus for the
disproportionation process of colophony, the following factors and
characteristics must be taken into account: 1) the catalyst gradually
loses its activity and must be periodiGally replaced by a fresh one; 2)

in order to maintain the necessary depth of traaefornation and the given
output of the apparatus of continuous action of the process, the
temperature conditions of the process should change with the time; 3) the
positive thermal affect of the reaction calls for a regenerating heat-
remover. The principle diagram of the set-up is given in Fig. 9. This
sohome is thought to be typical. The quality of the disproportionated
colophony as an emulsifier for the productionLof butadiens-styrene rubber
Was tested. rt was found that the suspended dust-like particles of the
catalyst, such as the nickel or palladium particles are present only in
the first samples of colophony, rinsing the surface of the freshly-
suspended catalyst grains.' After 0.5-1.0 hra of the catalyst action,
the yielded:produot is, almost completely devoid of any suspended particles.
Various samples ootained during the process of "cold" copolymerization
of butadione,and styrene according to the trilon-rongalite composition
were tested according to the ampoule method, in order to establish the
effect on the colophony emulsifiers' "activity" of the conditions of the
process of colophony disproportionation. It was shown that the Goloplaony
obtained with a nickel catalyst, both directly as well as after fraction-
ating, is muoh inferior in "activity" to the American preparation

catalyst after fraotionation has about the same rate of polymerization
as "Dresinate-214". Thus, the process o)~ disproportionation with

TEXT: The mechanism of decomposition of iso-pro y1 benzene hydro-
gen peroxide with concentrated sodium hydroxide ffirst stage inoc-
methyl styrene production) has not so far been explained satisfac-
torily. It was, therefore, necessay to conduct a detailed study of
the properties of the aqueous sodium salt of iso-propyl benzene hy-
drogdn peroxide which according to the earlier works represents a
primary intermediate product, The usual decomposition is conducted
in heterogeneous two-phase systems and in the first place the BO_
lubility of the aqueous hydrogen peroxide salt in both the phases
must be considered. It was found that at 200C the solubility of the

The decomposition of iso-propyl ... D227/D301
salt decreased as the concentration of NaOH increased. In the two-,
phase system this would cause the displacement of the salt into th
hydrocarbon layer. The solubility of the hydrated salt in iso-pro-
pyl benzene has been found to increase with temperature which means
that under the conditions of decomposition (elevated temperature
and highly concentrated sodium hydroxide) most of the salt could be
found in the hydrocarbon layer. To establish the quantitative rela-
tion8hip between the rate of decomposition and the ratio of free
and bound hydrogen peroxide the authors conducted kinetic mersure-
ments using predetermined ratios of the latter. The results showed
that at 800C the highest rate of reaction corresponded to the molar
ratio of hydrogen peroxide to its salt of 2:16 while the pure so-
dium salt decoieosed at half that rate. At 50 C the decomposition
of the pure salt did not occur which indicated certain changes tak-
ing place within the reaction system. To verify this statement a
mixture of free hydrogen peroxide and its hexahydrated salt in i8o-
propyl benzene, in which the ROOH:ROONa ratio corresponded to the
highest rate of reactiong was heated to 6000 and cooled rapidly.
Well defined rectangular crystals were obtained. When the same

systeln was heated to 50 OC a;id cooled rapidly,prismatic crystals
were formed. Chemical analysis of both products showed that in the
first case a trihydrated salt was obtained while in the second no
change occurred. Heating pure JaexAhydrated salt to 8000 gave an
unchanged product, showing that the separation of three molecules
of water during the reaction with hydrogen peroxide is due to the
per-solvation with the formation of thehydrated form of free iso-
propyl benzene hydrogen peroxide. The existence of such a salt has
so far been unknown. It mayq therefore, be assumed that similar re-
sults would be obtained by replacing hydrogen peroxide with other
compounds capable of hydrate formation, e.g. dimethyl phenyl car-
binol which is formed as a result of the decomposition of iso-pr.-
pyl benzene hydrogen peroxide with alkali. Again the hexahydrated
salt and dimethyl phenyl carbinol were heated to 50 and 800C and
as expected prismatic and plate-like crystals respectively were ob-
tained. The reaction of pers~olvation of the hexahydrate of hydro-
gen peroxide when it is reacted with water acceptor A may be re-
presented as follows:

thors aimed at preparing an anhydrous sodium salt, The method used
consisted of reacting the hydrogen peroxide salt with sodium wire,
in ether, at -20 to -2500o After the removal of solventt dilution
with n-pentane and filtration of sodium and sodium hydroxide, the
product was analyzed and found to contain a mixture of dimethyl
phenyl carbinol and its sodium alcoholate. Further experiments were
concerned with determining a relation between the rate of the de-

composition of the iso-propyl Dhenyl benzene hydrogen peroxide and
free hydrogen peroxide. The compositions of the starting mixtures
were chosen so that the content of the dimethyl phenyl carbinol
.and its alcoholate in relation to the total quantity of free and
bound hydrogen peroxide were,constant. The kinetic curves for these
systems showed that the addition to the anhydrous sodium hydrogen
peroxide salt of free hydrogen peroxide (ROOH : ROONa = 1.23) not
only increased the rate of reaction, but also increased the limit
of conversion. Assuming that the anhydrous salt is also atablet
''the addition of free hydrogen peroxide would give rise to some re-
active intermediate compound which would determine the rate of re-
action, The existence of the limit of conversion results then from
the exhaustion of hydrogen peroxide and the thermal -tability of
residual sodium salt. This explanation appears to coatradict the
previous worki in which although the free hydrogen peroxide has not
been added, a reaction was observed. In that case, however, free
hydrogen peroxide might have been formed as a result of an exchange
reaction between the hydrogen peroxide salt and the carbinol,

The quantity of hydrogen peroxide formed is determined by the end
concentration of free dimethyl-phenyl carbinol. Assuming that re-
aztion (1) takes place, introduction of dimethyl phenyl carbinol
into the reaction should displace the reaction to the left and lo-
wer the limit of conversion. The results confirmed that this is
the case. In preparing the anhydrous sodium salt, separation of a
white solid was observed. The analysis showed that the solid re-
presented a compound of hydrogen peroxide and its salt or dimethyl
phenyl carbinol alcoholate. An attempt was then made to obtain the
solid directly by mixing equimolar quantities of hydrogen peroxide
and its anhydrous sodium salt at about OOC. The product proved hy-
groscopic but it was possible to obtain needle-like crystals, in
dry nitrogen. Chemical analysis of the latter showed that they re-
resented a compound in which the molar ratio of active oxygen

association of the complex, its molecular weight was determined by
the cryoscopic method,_:using dry benzene. The molecular weight co-
incided with the molecular weight of the dimer (ROONa . ROOH) 2; on
dilution, however, a reversion to the monomer was observed. The mo-
lecular weights of iso-propyl benzene-.hydrogen peroxide solutions
were also determined, finding that in very dilute solutions no as-
sociation of the compound occurs. When the concentration was in-
creased association occurred, but the molecular weight never reached
a maximum and-showed a linear increase within the experimental con-
centration range, indicating the formation of polymeric forms. For-
mation of the complex is ascribed to hydrogen bonding between the
hydroxyl group of the peroxide and one of the oxygens of its so-
dium salt. Infrared spectra shcwed that the strength of the hydro-
gen bond was considerably higher than for the free hydrogen per-
oxide. The absorption line for the free OH group was absent for 1 M
solution of the latter, while in the case of the complex this line
appeared for 0.1 M concentrations. There are 9 figures, 3 tables

salt (Denig~ reagent) yielded a comple?c s6lid salt which decompo:3od
explosively on hoating; decomposition of this complex (by treating
with 11C1) yielded an organic phase which was analysed and found to

the isopropylbenzone purif led from S-containing compounds rja3 much
higher than that of the non-troated nintorial; the 13opropylbenzone
peroxide content of the purified material after 6 lirs of oxidation
was 17%, while that of the untreated lsopropylbonzone was only 4~'U4;
moreover, the peroxide content of the purified isoprop,~lbenzen6 In-
creased on further oxidation,, while that of the nntreRted aqtorlal
dropped to about 1% aftcr 10 hrs of oxidotion. The inhibiting effect

was shown to be the same in both anhydrous and aqueous media# al-
though in the latter case the reaction was not accelerated in the

TEXT: The aim.of this woric was to study the influence of organic
acids on the rate and path of the oxidation reaction of iso-propyl-
benzene by H 202* Small quantities of HCOOH did not affect the rate
of this process; higher concentration (1905 % H060H) noticeably re-
tarded the reaction* This is thought to be due to-the destruction
of H202 by HCOOH with the formation of 0026 Acetic acid did ndt in-
:fluence the oxidation process but gallic and salicylic acids retar-
ded the oxidation while stearic and benzoic-acids accelerated the
reaction* The retardation effect of the hydroxy-acide is attributed
to their inhibiting action and to their ability to catalyze the de-

TEXT: The present paper is a continuation of earlier work (ZhOKh,

the initiation of the polymerization af styrene by thermally de.
composed A and B showed that free radicals may form during both
thermal and alkaline fissions of A and B. The alkaline fission in
anhydrous media of.A is believed to proceed by (1) formation of B6
largely by dipole-dipole or H-bond interactionst followed by some
dimerizationt (2) fission of the dimers

proceed m9inly by 0-0 fission and formation of ROO, whilst the al-
kaline fission is,chiefly the result of non-radical reaction (2).
An exactly analogous mechanism is proposed for the alkaline fission
of A in aqueous media@ In accordance with theoretical expectations,
experiments with the bydroxides of Nat K and Ba showed that the
rates of fission increased with increasing fielcl strength of the
cation# (ioe. Ba;;- Na ;:- K)t and were strongly decreased in the pre-
sence of large amounts of water (owing to the aqueous decomposition

ABSTRACT: A description is given ofmethads developed for investigating pulse
magnetic reversal of miniature cores*w"ith. a rectangular hysteresis loop in
magnetic fields corresponding to the ascending sector of the, full hysteresis loop.
A pulse program providing for magnetic reversal along the limit cycle acts upon
the core. In weak fields the viscosity processes in magnesium -manganese
ferrites strongly depend on temperature. Maximum viscosity coincides with
maximum permeability and is attained in the intensity region corresponding to the
initiation of magnetization. The design of the measuring system is described aad

tor, phantastron delay line) are prevented. Orig. art. has: 10 illustrations and a

TOPIC TAGS: hysteresis loop, magnetic hysteresis, pulsed magnetic field, ferrite
ABSTRACT: One of the methods for representing the pulse properties of ferrites is
the dynamic surface which is the set of phase curves d6ldt=f(b) at 11 =const for
M
transition processes during magnetic reversal of the core from the B r state by
positive square~-wave current pulses. The dynamic surface is considered for pulsed
al ternating magnetization of K-222 ferrite (3x2xl.5 mm) with 11 C--0.144 a/cm,
B r0.23 stl and intersection of the surface by planes B=const and 11=con8t. This
dynamic surface is strictly valid only for square-wave magnetizing pulses. It is
sho,.m that there is a region in direct proximity to the static hysteresis loop which
is characterized by extremely slow processes (tens of msec). Ductility in fields
