    Critical Temperatures and Pressures of Some Tetraalkoxytitaniums / E. D. Nikitin, A. P. Popov, Yu. G. Yatluk, V. A. Simakina // Journal of Chemical & Engineering Data. - 2010. - Vol.55, №1. - С. 178-183

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

    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

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
