摘要
在Ｅｌｌｉｓ平衡蒸馏器中测定了１０１．３２５ｋＰａ下甲醇（１）－乙酸异戊酯（２）、碳酸二甲酯（１）－乙酸异戊酯（２）和甲醇（１）－１，２－丙二醇（２）三对二元系的汽液相平衡数据。采用统计学方法对实验数据进行了热力学一致性校验。用改进的Ｐｅｎｇ－Ｒｏｂｉｎｓｏｎ状态方程计算汽相的逸度系数，液相活度系数用Ｗｉｌｓｏｎ和ＮＲＴＬ模型计算，对实验数据进行了关联。
The isobaric vapor-liquid equilibrium data for the binary systems of methanol(l)isoamyl acetate(2), dimethyl carbonate(1)-isoamyl acetate(2), and methanol(1 )- 1,2-propanediol(2) at101.325kPa are measured with an Ellis equilibrated distillator. Statistical method is applied to test thethermodynamic consistency. The experimental data can be satisfactorily correlated by the modifiedPeng-Robinson equation of state, which is applied to calculate fugacity coefficients for vapor phase,and Wilson and NRTL activity coefficient models, which are used to calculate activities for liquidphase.
