Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): critical constants --organic compounds --halogens
Аннотация: This review is part 11 of a series of contributions by the critical properties group of the previous IUPAC Commission I.2 on Thermodynamics, Subcommittee on Thermodynamic Data and the present IUPAC Project #2000-026-1-100, Critical Compilation of Vapor Liquid Critical Properties, sponsored by the Physical and Biophysical Chemistry Division. It presents all known experimental data for the critical constants of organic compounds containing at least two of the following atoms: B, Halogens (counted as one), N, O, S, and Si. Recommendations are given together with uncertainties. Critical temperatures have been converted, where warranted, to the ITS-90 scale

Аннотация: The critical temperatures and the critical pressures of aqueous solutions with mass fractions of hydrogen peroxide from 0 to 0.9 have been measured using the pulse-heating method applicable to thermally unstable substances. The critical temperature and the critical pressure of pure hydrogen peroxide have been determined by extrapolation. The results are compared with the values predicted by various methods

Заглавие : Critical properties of some tetraalkoxysilanes and tetraalkoxytitaniums with branched alkyl radicals
Место публикации : Fluid Phase Equilibria. - 2012. - Vol.331. - С. 1-5
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): branched alkyl radicals--critical properties --tetraalkoxysilanes
Аннотация: The critical pressures and the critical temperatures of tetraisopropoxytitanium, tetra-tert-butoxytitanium, and tetraisopropoxysilane have been measured. The decomposition of the substances studied begins at temperatures below their critical ones. A pulse-heating method which allows measuring the critical properties of thermally unstable compounds has been used. The times of heating from the beginning of a pulse to the moment of reaching the critical temperature were from 0.03 to 1 ms. The short residence times provided little degradation of the substances in the course of the experiments. The critical constants of tetraalkoxytitaniums and tetraalkoxysilanes with branched and straight alkyl chains have been compared. The experimental critical constants of tetraalkoxytitaniums and tetraalkoxysilanes have also been compared with those calculated using various group-contribution methods

Заглавие : Critical Temperatures and Pressures of Some Tetraalkoxytitaniums

Ключевые слова (''Своб.индексиров.''): critical pressures--critical temperatures--tetraalkoxytitaniums
Аннотация: The critical pressures and the critical temperatures of nine tetraalkoxytitaniums, Ti[O(CH2)nH]4 with n = 2 to 10, have been measured. All of the substances studied begin to decompose at temperatures below their critical points. The method of pulse heating applicable to thermally unstable compounds has been used. Residence times were from (0.03 to 0.46) ms, which resulted in little decomposition of the substances during measuring. The contributions of the titanium(IV) atom in the group contribution methods of Constantinou and Gani and Marrero and Gani have been calculated from the experimental data. The critical pressures and temperatures of tetraalkoxytitaniums have been estimated by these methods

Заглавие : Critical temperatures and pressures of straight-chain alkanediols (C3 to C12)

Ключевые слова (''Своб.индексиров.''): alkanediols--critical properties --pulse-heating method
Аннотация: The critical pressures pc and the critical temperatures Tc of diols with straight alkylchains HO(CH2)nOH and n=3, 4, 5, 6, 8, 9, 10, 12 have been measured. All the alkanediols studied decompose at near-critical temperatures. A pulse-heating method which allows measuring the critical properties of thermally unstable compounds has been used. The times of heating from the beginning of a pulse to the moment of reaching the critical temperature were from (0.03 to 0.46)ms. The short residence times provided little degradation of the substances in the course of the experiments. The uncertainties of the measurement of the critical properties of alkanediols are 0.04 pc and 0.015 Tc, where Tc is the absolute temperature. The critical properties obtained have been compared with the values measured earlier by various techniques. The experimental critical constants of alkanediols have also been compared with those calculated using the group-contribution methods of Lydersen, Wilson and Jasperson, and Marrero and Gani
