磷酸二氢钾催化合成乙酸异戊酯的研究

Synthesis of Iso-amyl Acetate Catalyzed by Potassium Dihydrogen Phosphate

在磷酸二氢钾催化剂存在下,由冰乙酸和异戊醇合成了乙酸异戊酯,当冰乙酸,异戊醇和磷酸二氢钾的物质的量之比为 1∶∶1. 5∶∶0. 096,回流时间为 120分钟,酯的收率达 91. 2%,磷酸二氢钾重复使用多次,催化活性没有下降.

Iso-amyl acetate was synthesis from acetic acid and iso-amyl alcohol in the presence of potassium dihydrogen phosphate catalyst.The yielding of the ester could reach 91.2% under amount of substance ratio of acetic acid, iso-amyl alcohol and potassium dihydrogen Phosphate can be reused for times without any less of catalytic activity.
