摘要: 用实验测定了NaCl、KCl、KBr三种盐在正丁醇-水、丁酮-水共8个三元部分互溶体系的液液平衡数据, 采用加盐饱和密度法进行平衡两相组成的分析, 并用Chen模型进行了关联。

Abstract: The LLE data of eight ternary systems (n-butanol-water and butanone-water with NaCl, KCl, KBr) were determined experimentally. A saturation-density method was proposed to determine the concentration of mixed solvents containing salt. The Chen model was used to correlate the LLE data satisfactorily.

Key words: Salting effect, n-butanol-water-salt system, Butanone-water-salt system, LLE date, Chem model
