采用金属负载型阳离子交换树脂作催化剂,正丁醇和乙酸为原料,对乙酸正丁酯的合成进行了研究,确定了最佳工艺条件:反应时间60min,原料摩尔比n(正丁醇)/n(乙酸)=1.1:1,催化剂用量占乙酸用量的40%,乙酸正丁酯的产率达到97%以上。 The synthesis of n-butyl acetate was studied by using metal-supported cation exchange resin as catalyst, n-butanol and acetic acid as raw materials. The optimum reaction conditions were as follows: the reaction time was 60 min, the molar ratio of n (Acetic acid) = 1.1: 1, the amount of catalyst accounted for 40% of the amount of acetic acid, n-butyl acetate yield of 97% or more.
