| 摘 要： | 使用斜式沸点仪测定1,3,5,7-四甲基环四硅氧烷在1.325～100.325 kPa范围内的饱和温度数据。采用非线性回归方法,利用EVIEWS 5.0软件得到1,3,5,7-四甲基环四硅氧烷的Antoine参数A、B和C的值分别为8.678 74、1 167.85和-93.579 K。由Antoine方程计算出的饱和温度与实验数据的绝对偏差为0.02～1.23 K。通过Clausius-Clapeyron方程计算得到1,3,5,7-四甲基环四硅氧烷在实验温度范围内的平均摩尔蒸发焓为41.17 kJ/mol,常压沸点为411.5 K。

| 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. |
