摘要
以固体超强酸TiO2/SO42-为催化剂,冰醋酸和正丁醇为原料合成醋酸正丁酯。考察了醇酸比,催化剂酸度,催化剂用量,反应时间,反应温度对酯化产率的影响.实验结果表明,在冰醋酸用量为0.1mol情况下,用固体超强酸TiO2/SO42-为催化剂,催化剂用量为0.80g,醇酸摩尔比为3,反应时间为3h,反应温度为120—125℃是最适宜的反应条件,酯产率可达到93.21％,实验结果较佳.
N-Butyl acetate has been synthesized from the basic materials glacier acetic acid and n-butyl alcohol by catalysis of solid ultrastrong acid TiO2/SO42-. The effect of acid-alcohol ratio, acidity of catalyst, amount of catalyst, reaction time, and reaction temperature were investigated. The experimental results showed that when 0.1mol glacier acetic acid was used, the most appropriate conditions were that 0.80g solid ultrastrong acid TiO2/SO42- was used as catalyst, alcohol-acid ratio was 3:1, reaction time was three hours, and reaction temperature was between 120 and 125℃. The yield of the ester was 93.21%, which was a satisfactory result.
