摘　　要：以乙酸和异戊醇为原料、对甲苯磺酸钙为酯化催化剂合成乙酸异戊酯,研究影响酯化率的因素.结果表明:当催化剂用量为0.6g,11.4mL乙酸与23.8mL异戊醇反应,带水剂环己烷为15mL,回流温度下反应120 min,此条件下反应酯化率可以达到96.9%.lsoamyl acetate was synthesized with acetic acid and isopentyl alcohol by using Ca（p-CH3C6H4SO3）2 as catalyst. The results showed that the esterification efficiency was 96.9% when the mole ratio ofisopentyl alcohol and acetic acid was 1,2：1, reaction time was 120 minutes, and the amount of catalyst was 0.6g in reflux temperature.
