Заглавие : Vapor-liquid critical properties of some tetraalkoxysilanes
Место публикации : Journal of Chemical & Engineering Data. - 2008. - Vol. 53, № 6. - С. 1371-1374
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): vapor-liquid
Аннотация: The critical pressures and the critical temperatures of ten tetraalkoxysilanes (tetraalkyl esters of silicic acid) Si[O(CH2)nH]4 with n = 1 to 10 have been measured. All 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 1) ms, which resulted in little decomposition of the substances during measuring. The experimental critical properties of tetraalkoxysilanes have been compared with the values estimated by the group-contribution methods of Lydersen and Nannoolal et al

Место публикации : Journal of Chemical & Engineering Data. - 2007. - Vol. 52, № 1. - С. 315-317
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): vapor-liquid
Аннотация: The critical pressures and temperatures of phenol and three phenylalkanols C6H5(CH2)nOH with n = 2 to 4 have been measured. These substances are thermally unstable at their critical points. The pulse-heating method with ultralow residence times has been used. Residence times are from (0.03 to 1) ms. The experimental critical properties of phenol and phenylalkanols have been compared with the values calculated using the group-contribution methods by Constantinou and Gani and by Marrero and Gani

Заглавие : Vapor-Liquid Critical Properties of n-Alkylbenzenes from Toluene to 1-Phenyltridecane
Место публикации : Journal of Chemical & Engineering Data. - 2002. - Vol. 47, № 4. - С. 1012-1016
ББК : 54
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Ключевые слова (''Своб.индексиров.''): carbons --n-alkylbenzenes --1-phenyltridecane
Аннотация: This paper gives experimental critical temperatures and pressures of 10 n-alkylbenzenes C6H5CnH2n+1 with the number of carbons in the side chain n = 1, 2, 4, 5, 6, 7, 8, 10, 11, and 13. n-Alkylbenzenes that are heavier than butylbenzene are thermally unstable at their critical points. The method of pulse heating of a wire probe placed into the liquid under study has been used. Residence times are from (0.01 to 1) ms. Equations for the correlation of the critical temperatures and pressures of n-alkylbenzenes with the number of carbon atoms in the side chain, molar mass, and normal boiling point have been obtained. The experimental critical constants of alkylbenzenes have been compared with the values calculated by the methods of Lydersen, Joback and Reid, and Constantinou and Gani

Заглавие : Vapor Pressures, Enthalpies of Vaporization, and Critical Parameters of a Series of Linear Aliphatic Dimethyl Esters of Dicarboxylic Acids
Место публикации : Journal of Chemical & Engineering Data. - 2006. - Vol. 51, № 5. - С. 1896-1905
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): vapor pressures
Аннотация: Vapor pressures and the molar enthalpies of vaporization of the linear aliphatic dimethyl esters of dicarboxylic acids CH3-CO2-(CH2)n-CO2-CH3 with n = (0 to 8) have been determined by the transpiration method. A linear correlation of enthalpies of vaporization (at T = 298.15 K) of the esters studied with the number n and with the Kovat's indices and has been found. The critical temperatures and pressures of the esters with n = (0 to 6) and n = 8 have been measured by the pulse-heating method with the residence times ranging from (0.03 to 1) ms. Experimental data on the critical properties are compared with the estimations by group contribution methods by Constantinou and Gani and by Marrero and Gani. Both methods considerably underestimate the critical temperatures of the esters studied; however, the method by Marrero and Gani provides the prediction of the critical pressures of the esters with an average absolute error approximately equal to the uncertainty of the measurements. ??

Заглавие : Thermodynamic properties of metastable liquefied inert gases: Part 2. P, T-properties of superheated krypton
Место публикации : Physica B: Condenced Matter. - 1989. - Vol.160, №2. - С. 221-230
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): krypton--inert gases--thermodynamic properties
Аннотация: The paper presents the results of investigations of the P, ϱ, T-properties of krypton in stable and metastable phase states. Experimental data have been obtained in a temperature range from 150 to 200 K and pressure range from 5.3 MPa to pressures close to the boundary of spontaneous boiling of superheated liquids. The method of pycnometry was used to measure orthobaric densities (116–160 K). The problem of the equation of state and stability boundary of metastable systems is discussed. An equation of state for the superheated liquid has been obtained in the framework of the mean-field theory and thermodynamic perturbation theory. The spinodal has been approximated
