ABSTRACT: Compared to the amines of the aliphatic series aromatic
amines have weaker basic properties since the presence
of the electric ne-ative benzene nucleus in the molecule
of the aromatic amine reduces its tasicity~ The basic
properties of the secondary, purely aromatic; amines e~ g.
in the case of diphenyl amine where the molecule contains
two benzene nuclei,, are especia3ly strongly reduced. For
znis reasong it was of special interest to investigate the
character of the Interaction. of diphenyl amine and materials
ahowing acid properties. The authors have recrystallized
3 times d1phenyl amine from petroleum naphta and dried it
Card 1/3 with warm air in tha exsiocator. The pure product had its

melting point at. 530C. The investigation of fusibility
and the determination oil' melting temperaturee of the
pure materia3s was eaTried out by means of the visual
polythermal method, Density was measured by means of a
pycnometer by Ren?o with a small stem and a volume of
4,5 milliliters. Viscosity was determined in the closed
viscosimeter by Ostval;d, The electric conductivity was
measured by means of the method by Kollraush in. a closed
-ontaine.c with smooth platinum electrodes, Measurings of
ilensity of viscosity and electric c!onductivity were carried
out in the glycerin thermosta-~,. This madp it possible to main-
taj-D, tpmperatures within, the rang,:~ of+0,1."% . For the prepaw
fhe single weighed
ration of the mixtures the method of t
portions was applied~ Computation of the concentration was
made in molar percents and viscosity in centi poises. The
system. diphenyl amine - monochloracatic acid which has not
been investigated. before was investigated by the authors as
t1o their fusibility (Fig. "1')I Equally, the system diphenyl
amine - traebloracetic acid was investigated by the authors
for the first time and their fusibility, viscosity, density
Card 2/3 and specif'j.c conductivity (Fig. 2) were determined, Diphenyl

amine - p - nitrobenzoic acid was investigated as to
fusibility (Fig. 3), Also diphenyl amine salicylic acid
was investigated only as to its fusibility (Fig. 4). The
same also holds for diphenyl amine succinic acid (Pig. 5)
and diphenyl amine adipic acid (Fie. 6). The diagrams set
up for the mentioned system - except for the system with
succinic a-,id - indicate the lacking of chemical interac=
tions between the components. It was found that the pre=
sence of 2 benzene rings in the molecule of diphenyl amine
strongly reduces its complex-forming ability.

sympathetic node in the cranium, with the exception
of the madial,, and that the most powerful of these
nerves is the inner carotid nerve. Within the composi-
tion of the latter there are connective branches leading
to the 3rd, 4th, 5th and 6th pairs of cranial nerves.
In the composition of the outer carotid nerve of cattle
there are sympathetic fibers for all of the salivary
glands without exception as well as gray connective
branches which lead to the pharyngeal branch of the

TITLE: The Determination of the True Constant of Rates in the

ABSTRACT: In acid-catalytic transformations the basicity of the molecules
of the reagent and the reactivity of the protonized forms are
the most important factors that influence the course taken by
reactions. Investigation of these factors is one of the main
problems in the theory of acid catalysis. Previous papers
dealing with this subject are dealt with in short. Works
hitherto carried out in connection with the reactivity of
alGohols have, according to the authors# opinion, the
disadvantage that reaction rates are compared at different
concentrations of the reacting particles. In order to avoid
this mistake, the authors chose solutions of HCI in waterless
alcohols as experimental objects. In these solutions only the
Card 1/4 solutions of alcohol are, of course, protonized. In the case

of sufficient dilution, the HCI-molecules are nearly totally
dissociated, and theiefore the concentration of the ions of
alcoxonium (alkoksoniy) will in practice be equal to the
stoichiometric concentration of the acid. Under the conditions
prevailing in this case, only alkyl-halides are formed by the
dehydration of the alcohols as end products. The reactions
occurring in the systems investigated can be described by the
scheme ROH + HC1 z=t ROH+-Cl- *---t ROH+ + Cl-. In diluted solutions

equilibrium is shifted to the right. It further holds that

tertin butyl alcohol. The investigation was carried out at
65 - 95 and at various initial concentrations of the HCl

table by way of example shows the results for n-butyl-alcohol.
Analogous results were obtained also for other alcohols
investigated in this connection. With the investigated
experimental conditions prevailing, the monomolecular
mechanism predominates. For various alcohols a diagram
shows the dependence of the constants found on the temperature
for the initial HC1 concentration.,-0.03. The activation energies
of most of the alcohols investigated did not differ essentially
from one another. Only in the case of isobutyl-alcohol
activation energy is considerably lower. It may be thit in this
case the reaction develope.according,to another and more
complicated mechanism, and the values found for the constants
perhaps do not correspond with the true values. The considerable
differences between alcohol dehydration rates in aqueous acid
solutions are essentially determined by their different
degree of protonization. There are I figure, 2 tables, and
13 references, 6 of which are Soviet.

TITLE: Determination of the True Constants of the Decay Rate of

TEXT: It -.is the purpose of the present work to determine the true
constants of the decomposition rate of alkoxonium ions of a series of
aliphatic alcohols: ethyl-, n-propyl-, isopropyl-, n-butyl-, iso-butyl-,
and tert-butyl alcohol, and thus also of the reactivity of these ions.
For this purpose, the formation rate of alkyl halides for l[Cl-soluticns
in water-free alcohols was investigated, viz. at various IfCl-concentra-
tions (from O.G3 to 1-5 N) in the temperature interval of from 65 to
950C. The investigations were carried out in ampoules which had been
placed into a liquid thermostat, whose temperature was kept constant

~,ias used; the indicator used was methyl red. Mainly the dependence of
the formation rate of alkyl halides on the initial concentration of
the HC1 in water-free alcohols as well as the temperature dependence
of the reaction rate were investigated. The results obtained for HCl
solutions in ethyl-, n-propyl-, iso-propyl-, n-butyl-, and isobutyl
alcohol are given in Tables 1-6. In these tables the rate constant values
k1 calculated from the equation of the monomolecular reaction at various
temperatures and different initial concentrations of HC1, the calculat-
ed values of the factors of the exponential functions k 0, and the acti-
vation energies E are given. The character of the relation between the
formation rate of the alkyl halide and the initial HC1 concentration
is0comolicated. Table 7 gives the values of monomolecular constants for
70 , the factors of the exponential function, and the activation ener-
gies, as well as of the decomposition of the protonized molecules of
various alcohols. The values k1, ko, and E found for isobutyl alcohol
can, however, not be considered to be characteristic of the decay rate

of the iso-C4H 9OH 2-ions. From the data found it follows that the fac-
tore of the exponential functions for the ion decay C2H5OR2, C3H 7OH 2#
C H OH + (CH CHOH+, and (CH ) COH+ have values of from
4 9 29 3)2 2 3 3 2
2.8-10 12 to 2.5-10 14 sec-1, i.e., that lie near the theoretical value
for monomolecular reactions. The activation energies of the decay of
these ions are within the range of from 28,000 to 31,000 cal/mole
(Table 7). At the same temperature, the values of the rate constants
for the investigated alcohols differ by no more than the tenfold
(cf. Table 7). The great differences found for the rates in the dehydra-
tion of the alcohols by means of aqueous acid solutions, cannot be
explained solely by the different reactivity of the protonized alcohol
molecules, but iep in a high degree, determined by the different basici-
ty of the alcohols, i.e., by the parameters of thermodynamic, not
kinetic, character. There are 7 tables and 18 references: 7 Soviett

the propylene obtained at 3700C by dehydration of isopropyl alcohol by
means of Al 20 3' it was passed through columns 8 filled with alkali,
Mg(ClO 4)2 , and P2051 and subsequently frozen by using liquid N 2* After the
propylene had been thawed, the medium fraction was dried by Na wire. The
alkyl halides were distilled twice. TiCl 3 was prepared according to
G. Brauer (Ref. 6: Rukovodstvo po preparativnoy neorganicheskoy khimii.
(Manual of Preparative Inorganic Chemistry) Izd. in. lit., M., P- 547).
Polymerization was performed at 40-700C and at a propylene pressure of
170-300 mm Hg In th; reaction vessel. The reaction rate was determined fran
the consumption of propylene. It was found that polymerization proceeds in
two stages: a) unsteadily with increasing rate; b) steadily at a constant
rate. The time T 1/2 needed for reaching half the steady rate is a function
of pressure: T 112 ~ Q/pr,3H6 (4). T1/2 increases as follows:
