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.
- iron caproate,
- ethanol,
- chemical complexation extraction
