吗啡啉-正丁醇体系等压汽液相平衡研究

Study on isobaric vapor-liquid equilibrium for morpholine-1-butanol's binary system

采用泵式沸点仪测定了吗啡啉-正丁醇二元体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与实验值符合良好,所得数据通过了热力学一致性检验。

Morpholine-1-Butanol Binary system Vapor-liquid equilibrium date were measured with a new pump-ebulliometer in 101.3 KPa. The equilibrium composition of the vapor phase had been calculated form 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 date and the vapor-liquid equilibrium date for the binary system passed the thermodynamic consistency check.
