TITLEs New method of N-dimethyl-B-difluoro borazene synthesis
PERIODICALs Akademiya nauk SSSR. Izvestiya. Otdeleniye khimicheskikh
nauk, no. 2, 1962, 366
TEXT: The new method consists in the separation of hydrogen fluoride from
N-dimethyl-B-trifluoro borazane heated with aluminum dust in vaseline oil
medium. C 2 H7NBF3(boiling point 149 1500C (5 mm, Hg), dry aluminum dust,
and vaseline oil (boiling point 210 2300C (2 mm Hg)) were slowly heated
in a distilling flask on Wood's alloy. At 2780 hydrogen started separating
energetically and the collecting vessel connected with the gasometer by way
of a cooling trap rapidly filled with white brilliant N-dimethyl-B-difluoro
borazane crystals. Owing to the vaseline oil the course of the reaction
6(CH 3)2NH.BF3+2AI-6(CH 3)2NBF2+2AIF3+3H2 was very smooth and easy to control.
Yield of N-dimethyl-B-difluoro borazenei 85 - 88%. Some compounds of the
type R2N BF2? which are still being examined, were obtained in a similar

TITLE: Bronometric Methods of Determining Unsaturated Hydrc-
carbuns in Isopentane-Isoprene-laoamylene Mixtures
(Opredeleniye nepredellnosti izopentan - izopren -

(USSO
ABSTRACTz In the catalytic dehydrogenation of isopentane a mixture of
5 components forms - the initial product, 3 isopenzenes and
isoprene. The quantitative relation of the components depends
on the reaction conditions. In the present paper the relia-
bility of the three bromimetric methods - according to
Rosenmund (Reference 3), Gallpern (Reference 5) and Vyrabiants
(Reference 6) is examined. This control was investigated in
pure C -hydrocarbons and also in various artificial mixtures
of iso~entane with isopentenes and isoprene shich differed in
the number of components and also in their concentration. It
Card 1/5 became evident that the method according to Vyrabiants is not

75-1-23/26
Bromftetric Methods of Determining Unsaturated Hydrocarbons in isopentane-

suitable for an analysis of such mixtures, because the error
assumes different values and attains up to 7 - 8 % (absolute).
The results obtained according to Rosenmund and Gallpern conv
firm the fact that the accuracy of the determination of double
bonds depends on the structure of the hydrocarbons and on the
composition of the mixturet 2-methyl-butene(2) and 3-methyl-
butene(l) without difficulty absorb I bromine molecule on
bromination. 2-mothyl-butene(l) and isoprene consume more
than 1 bromine molecul --id therefore yield too high results,
relative to a double ~_A, in the determination according to
Rosenmund and Gallpern. The analysis of mixtures with 3 or 4
components, but without isoprene, showed an average absolute
error of the determination of the olefines of + 1 %. On addi-
tion Of iSODrene to the mixtures with 3 components the ab-
solute error increases to + 3 %. The analysis of mixtures with
5 components showed that the absolute error in the case of an
isoprene content up to 20 % in the method accordinp to Rosen-
mund on the average amounts to + 3 % and according to the
Card 2/5 method by Gallpern -2 /'~. As the average error in the

75-1-23/26
Bromometric Methods of Determining Unsaturated Hydrocarbonn in Iso-

letermination of the total number of double bonds in
mixtures of 5 components according to both methods has a
systematic nature, it can be taken into account by the intro-
duction of a corresponding coefficient (in the case of an
i8oprene content up to 20 %). It was shown that the valuea
for the total number of double bonds which were once de-
termined according to nosenmund and once according to
GalApern practically coincide after the introduction of a
correction coefficient. As the method of bromination only
makes possible a sum determination for alkenes and dienes,
the content of monoolefines can only be determined from the
difference between the total nimber of double bonds and the
content of dienes. In the present case an appropriate cor-
rection which takes into account the content of isoprene must
therefore be applied to the bromimetric results for determin-
ing the content of isopentenes. For the determination of iso-
prene the photometric method according to Robey and Wiese
(Reference 17) was employed which is well applicable in the
Card 3/5 presence of monoolefinea, but also of some dienes. The averaCe

error of this determination is less than 1 ~. (absolute).
Determination takes 1 1/2 hours, which time can be shortened
in series determinations to 20 minutes for one deter-mination.
When the concentration of isoprene in isopentane-isoprene-
isopentene mixtures has been determined in this manner, the
content of isopentenes (P) can be calculated according to the
formula P - a.Pl-b. P is the found total number of double
bonds in the mixture, b is the concentration of isoprene in
the mixture and a is the correction coefficient. In the method
according to Rosenmund a w 0,96 and in the method according
to Gallpern a = 1,04. All performed tcsts are exactly de-
scribed. During the elaboration of this method a short
article by Timofeyeva and collaborators (Reference 18) on the
same problem was published. In this article a correction co-
efficient is introduced in the final formula of the calcul-
ation which only takes into account the error produced by the
inexact bromination of i9oprene.

ABSTRACT: At present micro and macro-methods exist In this technique,
the principle of which was for the first time proposed by Bereer

fications of the methods applied hitherto for the purpose of
precising the measuring technique wereperformed. Containers, a
figure of which is given, and the weighine method according to
MacBen were employed. The somewhat modified micro-method of
determination according to Barger-Haat (Refs 2,5) was found to
be the most accurate and most convenient one. The experimental
technique employed is described. It appears that a mixing of

the degree of accuracy of the method. The results are j;iven in

applicable to molecular weights of up to 50000. Finally thanks

ABSTRACT: The present paper deals with the procuring of experimental
proof of the reactions of the destruction and structural
formation by the action of an ionizing radiation upon polyamides.
The soluble mixed polyamide "Anid G --669", which is produced by
polycondensation of hexamethylene diamine with adipic acid and
mitazelaic acid as well as with caprolactate, was used as
experimental object. The samples of 1 mm thickness of
"Anid G -669" were irradiated for I - 20 hours in air and also
in a vacuum. An X-ray tube of the type TRB -3 was used as
radiation source. A diagram shows the thermomechanical curves
of the compression of the samples of "Anid G -6691, as a function
of the dose. Already after three hours of irradiation a fraction,

the portion of which increases to 76~ after being irradiated for
10 hours. The second diagram shows the dependence of the
viscosity of the solutions on their concentration for
"Anid G -6691, in creosol and in acetic acid. As a result of
irradiation, the viscosity for creosol solutions decreases and
it increases for solutions in acetic acid. Two further diagrams
show the results ibtained by the turbidimetric titration of
non-irradiated and irradiated "Anid G -669" in form of integral
and differential distribution curves (with respect to
solubility)oThe maximum of the original differential
distribution eux:ve divides into a double maximum as a result of
irradiation. The distance b.etween the two maxima increases with
an increase of the doeeo If the dose is 'larger than that
corresponding to the forming of a YeAlow color, the differential
distribution curves correspond to the distribution over
solubility within the brine fraction. The experimental data
obtain 'ed by the present paper show the following: Under the

A complex investigation of the change of the mechanical
properties and of the properties of the solutions, as well as
of the distribution function with respect to molecular weighte
makes it possible to give a sufficiently complete estimate of
the change of the molecular structure of polyamides during their
radiation-chemioal transformation. Apparentlyl the application
of similar investigation methods makes it possible to separate
the parallel reactions of structural formation and of the
destruction of polymers of different structures. There are

TEXTt The authors studied the solutions of polydimethyl siloxane in
chloro benzene and benzene at 20, 30, and 40OCs and in isooetane at 20 and

yielded six fractions, the molecular weight of which was determined by
light scattering. The results are given in Table 1. The viscosity of the
polydimethyl siloxane solutions in chloro benzene at 20, 30, and 400C is
represented graphically in Fig. 1. The molecuJar weight of polydimethyl
Biloxane was calculated from the relation

where S - sedimentation constant, D = diffusion coefficient, R - gas con-
stant, T - temperature in OK, v - specific partial volume of the polydi-
methyl siloxane and ~ = its density. The viscosity of polydimethyl siloxane
solutions in chloro benzene, benzene and isooctane at 20, 30, and 400C
are shown graphically in Figs. 2 and 3. The viscosity of polydimethyl
siloxane solutions in chloro benzene at 20 and 400C and benzene at 200C is
a linear function of the concentration. By detormining the viscosity and
molecular weight, the authors obtained the constants X and a of the
j which gives the relatInn between the intrinsic viscosity

and the molecular weight. In Fig- 4, loglnl is plotted against log M for
polydimethyl siloxane in chloro benzene and benzene. The dependence of

for chloro benzene solutions of polydimethyl siloxane at

between the chain ends of polydimethyl siloxane in chloro benzene and
benzene increase with an increase in temperature. The constant A, which
des ignates the ratio of the hydrodynamic diffusion and viscosity radii of
macromolecules, was calculated from the relation
A ./QOT-TD(MEPQ))1/3, where n2o is the viscosity of the solvent in' poise, T
the temperature in OK, D the diffusion coe "fficient, M the molecular weight
of the polymer and [V the intrinsic viscosity. In the case of the chloro
benzene solutions of polydimethyl Biloxane, A changes little with tempera-
ture variation, i.e. by 2.27-10- 10 to P.8.1o~ 10 erg/degree. The relation
between the diffusion coefficient,'D, and the molecular weight of the poly-
mer, M, was calculated and expressed as D - 1-05-10- 4M-0-547

-TOPIC TAGS: siloxane, pz;lyphenylsiloxane, benzene, toluene, xylene, dinil, eye,olinear
polymer, phenyltrichlorosilane, infrared spectrum, polymer structure
ABSTRACT: Polyphenylsiloxanes obtained by condensation of the hydrolysi-- products of
phenyltrichloro si lane in four solvents (benzene, toluene, xyleno and dinil) were investigated
by infra-red spectroscopy. All four polyphenylsiloxanes were found to have the same cyclo-
linear structure predicted by Brown, et al. (J. Amer. Chem. Soc., 82, 6194, 1960).
The molecular weight of the polymer was 4. 1 x 106. The effect of the reaction mediltni on
the m,;,-!hanical properties, the degree of polymolecularity and the structural homogeneity
of polyphenylsiloxanes was studied in detail. The fou.- test samples were fractionated from
0. 5% benzene solution with methanol at 20C. Infrared spectra were then taken for all four
polymers, their thermal properties were studied and the molecular weight was determined
by light diffusion. The molecular weight distribution curves are plotted. The polymers
I .were found to be rather stable during fractionation. The infrared spectra show that the

mechanical properties of the polymers were not affected by the solvent. All four polypiwayl,
siloxanes had a very high glass temperature (TO=300C). The close T. values for the Poiy-
phenylsiloxanes show that the conditions of preparation do not significantly affect Vic struc--
ture. The reaction conditions also do not significantly affect the pDlydispersity of polyphonyl-
siloxanes. - The degree of pDlymolecularity and the average molecular weight of the Poly-
,'phanylsiloxanes increased, depending on t1io solvent used, in the order benzene-tolucrio-
;',xylene-dinil. A mechanism for the formation of these polyphenylsiloxanes is proposed.
