【摘要】：针对含0.015~0.03 g?mL~(-1)的N-羟基丁二酰亚胺(HOSU)水溶液,采用三辛胺(TOA)、正丁醇组成萃取剂,在单级液液萃取装置中通过实验筛选出最优萃取体系,考察了TOA的体积分数、两相相比、萃取温度、盐析剂等对HOSU在油水两相中分配系数的影响,并测定了该系统在25℃下的相平衡数据。红外光谱图分析结果表明TOA对HOSU的络合萃取同时存在氢键缔合和离子缔合两种形式。基于质量作用定律,建立了表达该萃取过程的相平衡模型,对25℃的萃取相平衡数据进行关联,结果表明有机相中HOSU浓度的实验值与模型计算值吻合良好。

The optimal extraction system was selected by experiments in a single-stage liquid-liquid extraction plant. The volume fraction of TOA was investigated and the two phases were compared. The effects of extraction temperature and salting-out agent on the partition coefficient of HOSU in oil-water phase were studied. The phase equilibrium data of the system at 25 鈩，
