以正丁醇和冰乙酸为原料,采用三氯化铝(AlCl3·6H2O)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。找到了一种无污染、催化活性高的催化剂——AlCl3·6H2O,确定了AlCl3·6H2O作为催化剂的最佳反应条件:醇酸比n正丁醇∶n冰乙酸=1∶0.7,催化剂用量为0.6g,反应时间为2.0h,产率高达98.6%(以0.2mol冰乙酸为基准);并且对催化剂的重复使用效果作了研究。
Using n-butanol and glacial acetic acid as raw materials, n-butyl acetate was synthesized by using aluminum trichloride (AlCl3 · 6H2O) as catalyst. The effect of catalyst amount, raw material ratio and reaction time on the reaction was investigated. AlCl3 · 6H2O was determined as a catalyst without pollution and high catalytic activity. The optimal reaction conditions of AlCl3 · 6H2O as catalyst were obtained: the ratio of n-butanol to n-acetic acid was 1: 0.7, the amount of catalyst was 0.6g, the reaction time was 2.0h, the yield was as high as 98.6% (based on 0.2mol glacial acetic acid); and the effect of repeated use of catalyst was studied.
