测定了DMC-CH_3OH,DMC-C_5H_4O_2,CH_3OH-C_5H_4O_2二元体系汽液平衡实验数据,利用二元体系的汽液平衡数据,运用C语言用NRTL状态方程模拟推算了碳酸二甲酯-甲醇-糠醛三元体系在常压下的汽液平衡,并对数据进行了关联。为建立精馏分离碳酸二甲酯-甲醇二元共沸体系的数学模型提供了必要的VLE数据。
The experimental data of the vapor-liquid equilibrium of DMC-CH 3 OH, DMC-C 5 H 4 O 2 and CH 3 OH-C 5 H 4 O 2 binary systems were determined. Based on the vapor-liquid equilibrium data of the binary system and the C language NRTL equation of state, the dimethyl carbonate- The ternary system is vapor-liquid equilibrium at atmospheric pressure and the data are correlated. It provides the necessary VLE data for the establishment of mathematical model for the separation of dimethyl carbonate - methanol binary azeotropic system by distillation.
