Study on synthesis of butyl acetate catalyzed by iodine

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%.
