摘 要: 为了满足化学工程设计的需求,文章采用斜式沸点仪测定了甲基苯基二乙氧基硅烷与邻二甲苯在5.325,10.325,15.325,20.325,25.325,30.325kPa下的汽液平衡数据.在相同的摩尔分数条件下相平衡的温度随着压力的增大而升高,呈现一定的规律性. In order to satisfy the estimation requirements for the development of the chemid engineering design, the vaporliquid equilibrium data in the binary system methylphenyldiethoxysilane and O-xylene at P= 5. 325, 10. 325, 15. 325, 20. 325, 25. 325, 30. 325 kPa are determined by inclined ebulliometer. The equilibrium temperature increases alone with the increasing of pressure at the same mole fraction, and the experiment results show some regularity.
