摘　　要：研究硫酸铈在合成丁酸戊酯工艺中的催化性能,考察硫酸铈用量、醇酸物质的量比、反应时间、带水剂用量及催化剂重复使用次数等因素对收率的影响。试验结果表明,硫酸铈具有催化活性高,易分离回收,操作简单,后处理方便等优势。最佳反应条件下收率为86.1%。硫酸铈是合成丁酸戊酯的良好催化剂。To study the catalytic activity of ceric sulfate in synthesizing amyl butyrate. Butyric acid and 1-pentanol reacted to form amyl butyrate by using ceric sulfate as the catalyst. The investigated effects inclueded amount of the catalyst, reaction time, molar ratio of alcohol to acid and repeated uses. Experimental results showed that the catalyst was efficient and environmental friendly. Under the best conditions its yield could reach 86.1%. Ceric sulfate is an excellent catalyst for synthesis of amyl butyrate.
