【摘要】 用泵式沸点仪测定了常压下四氯化碳—１ ，１ ，２ － 三氯乙烷在不同液相组成的沸点，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与实验值能很好的吻合．更多还原

【Abstract】 The boiling points of tetrachloro-methane and 1,1,2-trichloroethane binary system were determined at the atmospheric pressure with a motive magneto pump-ebulliometer. The equilibrium composition of the vapor phase had been calculated from TPX by indirect method. The model parameters of activty coefficient were correlated by the least square method. The calculated boiling points were in good agreement with the experimental data.更多还原
