【摘要】 本文用改进的Colburn汽液平衡釜测定了在760mm汞柱压力下,乙酸乙酯-苯-甲苯和四氯化碳-乙酸乙酯-苯两组三元体系的汽液平衡数据.乙酸乙酯-苯-甲苯三元体系的分析方法采用折光指数(n_D²⁰)和正常沸点两种三元物性数据相结合的物理化学分析法,四氯化碳-乙酸乙酯-苯三元体系的组成采用折光指数(n_D²⁰)和密度(d₄²⁵两种物性数据相结合的方法.将所测定的两组平衡数据与纯组分的参数有关的关联式计算所得结果进行对比,获得了满意的结果.更多还原

【Abstract】 The isobaric vapor-liquid equilibrium data at 760mm Hg of two ternary systems, ethyl acetate-benzene-toluene and carbon tetrachloride-ethyl acetate-benzene, are determined by a modified Colburn equilibrium still. The composition of ethyl acetate-benzene-toluene ternary system is determined from two properties, refractive index (nD20) and normal boiling point, while the composition of carbon tetrachloride-ethyl acetate-benzene ternary system is determined from refractive index (nD20) and density (d425). The experimental equilibrium data of two ternary systems are correlated by the equation obtained from copolymerization in the field of polymer chemistry with characteristic constants merely related with the corresponding pure components. The results of both two ternary systems are fairly satisfactory.更多还原
