摘要：

研究了丁酮乳化液膜体系中油水两相间液液传质系数、表面活性剂浓度、温度、搅拌速度等相关因素对体系液液传质的影响。实验发现表面活性剂在两相界面上形成单分子的界面层,该界面层在油水界面的传质阻力中占63％;温度及搅拌转速对体系的液液传质系数亦有影响,温度越高、搅拌速度越大,体系的传质系数越大。

Abstract:

The liquid-liquid mass transfer of butanone across an emulsion liquid membrane(ELM) was studied. The effects of surfactant concentration, temperature and stirring speed were also studied. The results showed that the mass transfer resistance of a surfactant monomolecular layer adsorbed on the oil／water interface accounted for about 63％ of the total mass transfer resistance. The liquidliquid mass transfer coefficient increased with an increase of temperature and stirring speed.

Key words: emulsion liquid membrane (ELM); butanone; liquid-liquid mass transfer
