【摘要】 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。更多还原

【Abstract】 LLE data of n-butyl acrylate-water, n-butanol-water binary systems at ambient pressure, and VLE data of n-butyl acrylate-n-butanol, n-butyl acrylate-butanol-water system at 2.67×10~4 Pa are measured. From the measured equilibriurn data of the above three binary systems, the NRTL constants are obtained, by which the VLE data of the titled ternary system are predicted. The predicted values are in good agreement with those measured, so the uniform correlationis is realized betweem LLE and VLE data.更多还原
