测定了丙烯酸正丁酯-水、正丁醇-水二元系在常压下的液-液平衡数据及200×1.333×10~2Pa下的丙烯酸正丁酯-正丁醇二元系和丙烯酸正丁酯-正丁醇-水三元系的汽-液平衡数据。由测定的三对二元数据求取了NRTL常数,并与三元实验数据进行拟合,计算值与实验值符合良好,从而使液-液平衡与汽-液平衡得到了统一的关联。
The liquid-liquid equilibrium data of n-butylacrylate-water and n-butanol-water binary system at normal pressure and n-butylacrylate-n-butanol binary system at 200 × 1.333 × 10 ~ 2Pa and acrylic acid N-Butyl-n-butanol-water ternary system vapor-liquid equilibrium data. The NRTL constants were obtained from the measured three pairs of binary data and fitted with the ternary experimental data. The calculated values were in good agreement with the experimental data, so that the liquid-liquid equilibrium and the vapor-liquid equilibrium were uniformly related.
