氯仿－正丙醇及其含盐体系的汽液平衡

实验测定了在１０１．３ｋＰａ压力下氯仿－正丙醇、氯仿－正丙醇－氯化锂及氯仿－正丙醇－氯化钙体系的汽液平衡数据。用Ｈｅｒｉｎｇｔｏｎ方法对无盐体系的实验数据作了热力学校验，并以ＶａｎＬａａｒ方程及Ｗｉｌｓｏｎ方程关联了无盐体系，结果较为满意。用汽液平衡盐效应方程计算了含盐体系在不同液相组成下的盐效应参数。提出了关联盐效应参数与液相组成的经验方程，并以经验方程及汽液平衡盐效应方程计算了平衡汽相组成，实验值与计算值吻合较好。

VLE DATA FOR CHLOROFORM-N-PROPANOL AND ITS SYSTEM CONTAINING SALT

he VLE data at 101.3 kPd are determined experimentally for chloroform-n-propanol, chloro- form-n-propanol-lithium chloride and chloroform-n-propanol-calcium chloride systems.The thermody- namic consistency of the expcrimental ddta for the system without salt are checked by the Herington method. The system without salt is correlated by the Van Laar and Wilson equations,and the results are satisfactory.The salt effect parameters for systems containing salt are calculated by the salt effect equation of VLE. An experimental equation is established for corrclating the salt effect parameter and the liquid phase composition. The equilibrium vapor compositions are calculated by the experimental e- quation and salt effect equation of VLE.The values calculated are in good agreement with the experi- mental one.
