摘要
利用新型泵式沸点仪,在101.3kPa下测定了甲基二氯硅烷-苯二元系在不同液相组成时的沸点;由所测的二元系数据,采用间接法由TPx推算了与之平衡的汽相组成,再用最小二乘法求出了该二元系的Wilson、NRTL、Margules、vanLaar四种模型的液相活度系数模型参数,关联结果令人满意.
This paper describes the measurement of the vapor-liquid equid equilibrium (VLE) data of methydichlorosilane - benzene system at 101.3 kPa with a new pump-ebulliometer. The equilibrium composition of the vapor phase had been calculated from TPx by indirect method.The model parameters of liquid activity coefficient of the Wilson, NRTL, Margules and van Laar equations were correlated by the least squaremethod, and the results were satisfactory.
