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 Investigation of Interaction Between Diphenyl Amine 79-28-4-4/6o and Organic Acids by Fhyis 'CuL~--jajca ~- Anij:vsid 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 Investigation of Interaction Between Diphenyl Amine 79-28-4-4/60 and Organic Acids by Axialysis, Methcds 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. There are 6 figures and 14 references. 12 of which are Soviet.

It was of interest to the authors to explain inhowfar the exchange of a benzene nucleus in the molecule of the secondary amine by a naphthalene nucleus could effect the convertabiiity with organic acids. The reaction of phenyl-p-naphtnylamine with organic acids has hitilerto riot been dealt with.

The fusibility, viscosity, density tind electric conductivity of the systems formed of phenyl-f3- -naphthylamine with trichlcrowetic acid vas investigated. From the phase diagrams of the system the process of conversion of the components in solid and liquid phase can be steun. The substitution of a benzene nucleus in the molecule of the secondary aromatic amine by a naphthalene nucleus does not exert any influence on the character of its conversion with organic acids.

TITLE: The Determination of the True Constant of Rates in the Decomposition of Aliphatic Alcohols (0predeleniye istinnykh konstant skorostey pri raspade alifaticheskikh spirtov) PERIODICAM Doklady Akademii nauk SSSR, 1959, Vol 124, Nr 1, PP 139-141 (USSR) 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 The Determination of the True Constant of Rates in the SOV/20-124-1-39/69 Decomposition of Aliphatic Alcohols 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 2 2 equilibrium is shifted to the right. It further holds that k ROH' -::4 R+ + H 0 (slow) , R+ + Cl----t RC1 (fast), 2 2 ROH+ + Cl- 2) R01 + H 0. The following aliphatic alcohols 2 2 were used for experimental purposess ethyl-n-propyl-alcohol, i-propyl-alcohol, n-butyl-alcohol, i-butyl-alcohol, and tertin butyl alcohol. The investigation was carried out at 65 - 95 and at various initial concentrations of the HCl Card 2/4 (from 0-03 to I-5N) by means of the usual ampoule method. A -The Determination of the True Constant of Rates in the SOV/20-124-1-39/69 Decomposition of.Aliphatic Alcol'ols 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.

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 ,.,-ith an accuracy of +0.2 0, For titration, a 0.02516 N NaOH-solution Card 1/4 Determination of the True Constants of the- S1076160,1034100910321'041XX Decay Rate of Alkoxonium Ions in the Inter B020/BO56 action Between Aliphatic Alcohols and Hydrogen Chloride ~,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 Card 2/4 Determination of the True Constants of the S/076/60/034/009/032/041XX Decay Rate of Alkoxonium Ions in the Inter- B020/BO56 action Between Aliphatic Alcohols and Hydrogen Chloride 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.

The authors' experimental method was applied (Ref- 5: A. P. Pirsov et al., Vysokomolek. soyed., 1, 1161, 1961). The a-modification of TiCl 3 was prepared according to G.

Polymerization was conducted at 30-700C and 220-585 mm Hg pressure, at a molar ratio of Be(c2H 5)2 to TiCl34zz'3.
