摘　　要：本研究以I2作催化剂,正丁醇和HAc通过酯化反应合成了乙酸正丁酯。考察了最佳原料配比,催化剂用量和反应时间对反应的影响。合成的最佳条件是:酸醇物质的量比为1.5∶1.0,催化剂用量为醇物质的量的10(mol)%(催化剂I2 0.6g),反应时间为4.0h。在最佳条件下,乙酸正丁酯的产率可达67.52%。Butyl acetate was synthesized by esterification with n-butyl alcohol and HAc,and with I2 as catalyst.The effect of best ratio of materials,amount of catalysts and reaction time were investigated.The best conditions were as follows： the amount-of-substance ratio was 1.5∶1.0,the amount of catalyst was 10（mol）% of n-butyl,the reaction time was 4.0h.The yield of butyl acetate reached 67.52%.
