The influent actors of reaction were investigated. The results showed that the appropriate conditions should be: Weight of catalyst was 0. 5g (weight of butyric acid if 0. 2mol); molar ratio of isoamyl alcohol to butyric acid was 1. 8: 1; reaction time was 2. 0 h; the taking water reagent (Toluene) was 15mL. The yield of isoamyl butyrate was about 99. 0%.展开更多
