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
