| Abstract: | Ethyl caproate was synthesized from hexanoic acid and ethyl alcohol with new Lewis acid ferric potassium alum as catalyst.The factors of influencing esterification rate were investigated.The results showed that ferric potassium alum was a good green catalyst for synthesis of ethyl caproate.The optimum conditions were:molar ratio of hexanoic acid to ethyl alcohol was 1∶ 2.4,amount of catalyst was 1.0 g /0.05 mol hexanoic acid,the water-carrying toluene was 10 mL,and the reaction time was 100 min.The highest esterification rate was 94.3%,and the catalyst can be recycled for many times. |
