    Vapor - Liquid Critical Properties of Some Tetraalkoxysilanes [Electronic resource] / E. D. Nikitin, V. A. Simakina, A. P. Popov // Journal of Chemical & Engineering Data. - 2008. - Vol. 53, № 6. - P1371-1374 : рис., табл. - Библиогр. : с. 1374 (17 назв.)

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

DICARBOXYLIC ACIDS -- CRITICAL TEMPERATURES -- CRITICAL PRESSURES -- PULSE HEATING
Аннотация: The critical temperatures and pressures of nine saturated straight-chain dicarboxylic acids HOOC(CH2)nCOOH with n = 2, 3, 4, 5, 6, 7, 8, 10, and 12 have been measured. All of the acids investigated are thermally unstable at their critical points. The method of pulse heating of a wire probe immersed in the liquid under study has been used. Residence times are from (0.01 to 1) ms. The experimental critical properties of dicarboxylic acids have been compared with the values calculated by the group-contribution methods of Ambrose, Joback, and Reid, Constantinou and Gani, and Marrero and Gani. ??

    Critical pressures and temperatures of n-diaminoalkanes (C2 to C12) [Text] / E. D. Nikitin, A. P. Popov, Yu. G. Yatluk // Journal of Chemical & Engineering Data. - 2006. - Vol. 51, № 2. - P609-611

Аннотация: The critical temperatures and pressures of eight n-diaminoalkanes NH 2(CH2)nNH2 with n = 2, 3, 4, 6, 8, 9, 10, and 12 have been measured. The method of pulse heating of a wire probe immersed into the liquid under study has been used. Residence times are from (0.03 to 1) ms. The critical properties of diaminoalkanes have been estimated by the group-contribution methods by Joback and Reid, Constantinou and Gani, and Marrero and Gani. These properties have also been calculated using a method based on the assumption that the functions describing the dependence of the critical properties of homologous series on the number of mers in a molecule should be self-similar and provide the scaling behavior for long-chain molecules. The last method provides the best accuracy in calculating the critical properties of diaminoalkanes. For this method, the average absolute errors are equal to 0.4 % for the critical temperature and about 2 % for the critical pressure. © 2006 American Chemical Society

    Critical temperatures and pressures of 12 phthalates using the pulse-heating method [Text] / E. D. Nikitin, A. P. Popov, Yu. G. Yatluk // Journal of Chemical & Engineering Data. - 2006. - Vol. 51, № 4. - P1326-1330
ББК 54
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The critical temperatures and pressures of phthalates with the straight side alkyl chains C6H4-1,2-[COO(CH2) nH]2 (n is from 1 to 11) as well as bis(2-ethylhexyl) phthalate have been measured. No literature data are available for the critical properties of phthalates. Since phthalates decompose at temperatures well below their critical temperatures, the method of pulse heating of a wire probe immersed into the liquid under study has been used. The method minimizes the effect of thermal decomposition because residence times are only from (0.035 to 1) ms. The experimental critical properties of phthalates have been compared with the values calculated using the group-contribution methods by Constantinou and Gani and Marrero and Gani ??

Аннотация: The critical temperatures and pressures of phenylalkanoic acids with a straight alkyl chain C6H5(CH2)nCOOH (n = 1 to 6) have been measured. The method of pulse heating of a wire probe placed into the substance under study has been used. The method minimizes the thermal decomposition because residence times are from (0.035 to 1) ms. An equation for the correlation of the critical pressures of phenylalkanoic acids with the number of CH2 groups between phenyl and carboxyl functional groups and molar mass has been obtained. The experimental critical constants of phenylalkanoic acids have been compared with the values calculated by the group-contribution methods of Constantinou and Gani and Marrero and Gani????

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

CRITICAL PROPERTIES -- TETRAALKOXYSILANES -- TETRAALKOXYTITANIUMS
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
