摘　　要：研究了以混合氯化稀土为催化剂,乙酸和正丁醇为原料合成乙酸正丁酯,并考察了影响反应的因素。结果表明:正丁醇与乙酸物质的量之比为2.5∶1,催化剂用量为0.25g,带水剂为环己烷,用量为2ml,反应时间1.5 h时,反应效果最佳,其酯化率可达95.98%。The synthesis of n- butyl acetate from acetic acid and n- butanol with mixed rare earth chlorides as catalyst was studied. The influential factors of reaction were investigated. Results show that the appropriate conditions are： molar ratio of n - butanol to acetic acid was 2.5 ： 1 ; Catalyst＇ s weight was 0.25g; Cyclohexane is used as water - carrying reagent with 2ml; Reaction time was 1.5 h. The yield of n - butyl acetat is about 95.98 % .
