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
