N 64 Nikitin, E. D. Vapor-liquid critical properties of some tetraalkoxysilanes [Текст] / E. D. Nikitin, A. P. Popov, V. A. Simakina // Journal of Chemical & Engineering Data. - 2008. - Vol. 53, № 6. - С. 1371-1374 Рубрики: ФИЗИКА Кл.слова (ненормированные): 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 \\\\Expert2\\NBO\\Journal of Chemical and Engineering Data\\2008, v.53, p. 1371.pdf |
C 89 Critical properties of some tetraalkoxysilanes and tetraalkoxytitaniums with branched alkyl radicals [Электронный ресурс] / E. D. Nikitin, A. P. Popov, Yu. G. Yatluk, V. A. Simakina // Fluid Phase Equilibria. - 2012. - Vol.331. - P1-5 Рубрики: ФИЗИКА Кл.слова (ненормированные): 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 |
