| Abstract: | Benzyl butyrate was synthesized from benzyl alcohol and butyric acid by esterification using ceric sulfate as catalyst. The effects of reaction conditions, such as such as catalyst amount, reaction time, molar ratio of alcohol to acid and various water-carrying agent, were observed. Under optimized conditions, i. e. , butyric acid 0.2mol, molar ratio of alcohol to acid 2.0, catalyst 0.5g, water-carrying agent toluene 20ml and reaction time 30min, the yield of benzyl butyrate reached 92.20%. The results show that ceric sulfate is an excellent catalyst for the synthesis of benzyl butyrate. |
