乙酸乙酯-乙醇-水-甘油体系中三元及四元体系的汽液平衡数据测定及推算(英文)

Measurement and calculation of three and four compounds VLE data for ethyl acetate-ethanol-water-glycerol

设计了液液平衡釜,测定乙酸乙酯-乙醇-甘油、乙酸乙酯-水-甘油及乙醇-水-甘油三元体系的VLE 数据;以Wilson 方程为平衡模型,由两对二元模型和三元体系的VLE 实验数据关联第三对模型参数;测定乙酸乙酯-乙醇-水-甘油体系的VLE数据,由二元模型参数及三元体系的VLE 实验数据计算乙酸乙酯-乙醇-水-甘油体系的VLE 数据并与实验数据比较;本文测定结果及计算结果为乙酸乙酯-乙醇-水、乙酸乙酯-乙醇体系的萃取分离模拟计算及试验提供基础数据。

Designing Liquid-Liquid Equilibrium pot.VLE data of Ethyl acetate-Ethanol-Glycerol et al.and Ethyl acetate-Ethanol-Wa-ter-Glycerol were Measured.The third Model parameters were Correlated by combining binary parameters of Wilson equation with VLEdata of ternary system.Thus,VLE data of Ethyl acetate-Ethanol-Water-Glycerol was calculated,Results of Measurement and Calcula-tion were Compared,which were Provide fundament data for Extraction Simulation Calculation of Ethyl acetate-Ethanol-water and Ethylacetate-Ethanol.
