1,3,5,7-四甲基环四硅氧烷饱和蒸汽压的测定与关联
Measurement and correlation of saturated vapor pressure of 1,3,5,7-tetramethylcyclotetrasiloxane
摘要
Abstract
The temperatures of 1,3,5,7-tetramethylcyclotetrasiloxane were measured from 1.325 kPa to 100. 325 kPa by an inclined ebulliometer. The Antoine parameters of 1,3,5,7-tetramethylcyclotetrasiloxane were regressed by the nonlinear regression method with EVIEWS 5.0 software,A =8. 678 74,B = 1 167. 85, and C = -93. 579 K, respectivly. The correlation between the saturated vapor pressure and the temperature was conducted with the absolute deviation ranging from 0. 02 K to 1. 23 K. The mean molar enthalpy of vaporization of 1,3,5 ,7-tetramethylcyclotetrasiloxane was obtained from the Clausius-Clapeyron equation with a result of 41. 17 kj/mol. The calculated normal boiling point was 411. 5 K.关键词
