摘要
用泵式沸点仪测定了常压下文题系统在不同液相组成下的沸点，通过间接法由ＴＰｘ推算与之平衡的汽相组成。用单纯形法求出了两个系统的液相活度系数模型参数，由模型参数推算的两个二元系的泡点和露点与实验值能很好的吻合。用模型参数推算了常压下水三聚甲醛系统的共沸组成和共沸温度。
The boiling points of two binary systems,trioxane-water and trioxane-1,2dichloroethane, were determined under atmospheric pressure with a pump-ebulliometer.The vapor-phase compositions were calculated from the TPx data by an indirect method.The model parameters of the liquid activity coefficient were correlated by the simplex method. The calculated boiling point and dew point were in good agreement with experimental data.The azeotropic temperature and compositions of the trioxane-water system under atmospheric pressure were also predicted.
