| 摘 要： | 以正丁醇和冰乙酸为原料,采用无水三氯化铝作催化剂合成醋酸正丁酯.考察了催化剂用量、原料配比和反应时间等因素对反应的影响.确定了无水三氯化铝作催化剂的最佳反应条件是n正丁醇∶n冰乙酸=1∶0 7,无水三氯化铝用量为醇酸总质量的3.0%,反应温度104～107℃,反应时间为2 0h,产率高达99 2%(以冰乙酸计).并且对催化剂的重复使用效果做了研究.

| Abstract: | n-Butyl acetate is preprared by n-butanol and glacial acetic acid with anhydrous aluminium chloride as catalyst.The factors on esterification yield such as:proper amount of catalyst,material ratio and time of reaction have been studied,The optimun conditions are as follows:n_(正丁醇)∶n_(冰乙酸)= 1∶0.7;mass of catalyst,0.6g;reaction time,2.0h; Yield of n-butyl acetate is 99.2%(based on glacial acetic acid).The reuse of catalyst is investigated. |
