摘要：用泵式沸点仪测定了常压下甲醇－水、甲缩醛－甲醇、甲缩醛－水三个二元系在不同液相组成时的沸点，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三个二元系的液相活度系数模型参数，由模型参数推算的三个二元系的泡点与实验值能很好的吻合。
The boiling points of three binary systems: methanol-water, methylal-methanol and methylal-water. were determined at the atmospheric pressure with a pump-ebulliometer. The vapor phase compositions had been calculated from TPx by indirect method. The model parameters of liquid activity coefficient were cortelated by the least square method. The calculated boiling points were in good agreement with the experimental data.
