摘要：用新型泵式沸点仪测定了常压下三聚甲醛－水二元系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反系数模型参数，由模型参数推算的泡点温度与实验值能较好的吻合。
The boils of the trioxane-water binary system were determined at the atmospheric pressure with a new motive cottrell pump-ebulliometer. The equillibria compeition 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 agrement with the experimental data.
