摘要
用气相单循环平衡蒸馏器测定了甲醇 ( 1) -碳酸二甲酯 ( 2 )物系的常压汽液相平衡数据 ,用积分法对其进行了热力学一致性检验 ,并用Wilson方程对试验数据进行了关联 ,得到了液相活度系数参数。测定了加入萃取剂草酸二甲酯 (DMO)对甲醇 ( 1) -碳酸二甲酯 ( 2 )
The atmospheric vapor-liquid equilibrium data of the binary system methanol dimethyl carbonate were measured.Integral method was used to test the thermodynamic consistency.The activity coefficient of the liquid phase was calculated by the Wilson equation and satisfactory correlation result of the experimental data was obtained.The effect of dimethyl oxalate on the vapor-liquid equilibrium of this binary azeotropic system was investigated.
