摘　　要：采用自制的硅胶固载硫酸铈为催化剂合成了己酸己酯,考察了催化剂用量、醇酸物质的量比、反应时间及带水剂用量等因素对收率的影响。结果表明,该催化剂具有催化活性高,易分离回收,操作简单,后处理方便,收率高等优点。适宜反应条件下收率为93.6%。By using cerium sulfate supported on solica gel as the catalyst, hexyl hexanoate was synthesized. The investigated effects included amount of the catalyst, reaction tune, molar ratio of alcohol to acid and amount of carrying water agent. Experimental results showed that it was the efficient, economic and easy to use. Under the best conditions its yield could reach 93.6%.
