| 摘 要： | 乙醇是重要的化工产品，一般通过发酵法和合成法生产，其在发酵液及合成液中的浓度较低［１～３］．一些工业过程产生的大量废水中往往含有微量乙醇，需要进行脱除或回收．传统上，乙醇的分离和回收多采用蒸馏法［１，４］．但稀溶液蒸馏需要消耗大量的能量．对于含微量醇...

| Abstract: | Solvent extraction of ethanol has been carried out by caproic acid, caproic acid containing iron caproate and toluene containing iron caproate based on the HSAB principle. Experiments showed that caproic acid containing iron caproate could give higher distribution ratio than single caproic acid, indicating that there is a strong interaction between iron caproate and ethanol. Distribution ratio of ethanol was greatly affected by the concentration of iron caproate, but slightly by initial concentration of ethanol. The mechanism of extraction is discussed. |
