以固体超强酸 SO42 - / Zr O2 - Ce O2 作催化剂 ,冰醋酸和正丁醇为原料合成了乙酸丁酯。采用正交实验法对影响反应的因素进行了考察。结果表明 :最佳反应条件为 n(醇 )∶ n(酸 ) =2∶ 1,催化剂用量为反应混合物总量的 1.5 %(质量分数 ) ,反应时间为 3h,酯化率可达 92 .6 %。
The butyl acetate was synthesized by using solid superacid SO42 - / ZrO2 - Ce O2 as catalyst and glacial acetic acid and n - butanol as raw materials. Orthogonal experiments were used to examine the factors influencing the response. The results showed that the optimum reaction conditions were n (alcohol): n (acid) = 2: 1, the amount of catalyst was 1.5% of the total mass of the reaction mixture, the reaction time was 3h and the esterification rate was 92.6 %.
