The effects of reaction time, catalyst amount,and ratio of glacial acetic acid to isoamyl alcohol were investgated. The results showed that at condition of molar ratio of HAc to isoamyl alcohol=1∶1 08, that of SnCl 4·5H 2O to HAc=1∶100, 150 ℃, 1 h isoamyl acetate can be obtained in yield of 95 6%.展开更多
The synthesis of isoamyl butyrate with isoamyl alcohol and butyric acid as reactants and rare-earth solid superacid SO42-/TiO2/La3+ as catalyst had been studied. The influent actors of reaction were investigated. The ...The synthesis of isoamyl butyrate with isoamyl alcohol and butyric acid as reactants and rare-earth solid superacid SO42-/TiO2/La3+ as catalyst had been studied. 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
