【摘要】 用泵式沸点仪测定了甲基二氯硅烷—甲苯二元系在常压下的汽液平衡数据，并用间接法由ＴＰＸ 推算了与之平衡的汽相组成，用最小二乘法求出了该系统的液相活度系数模型参数，由模型参数推算的泡点温度与实验值符合良好，所得数据通过了热力学一致性检验。更多还原

【Abstract】 This paper describes the measurement of the vapor-liquid equid equilibrium (VLE) data of methyldichlorosilane-toluenene binary 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 were correlated by the least square method.The calculated boiling points were in good agreement with the experimental data.更多还原
