摘要
用热浓硫酸处理硅胶,制备了硅胶负载硫酸催化剂,用冰乙酸与异戊醇的酯化反应考察了催化剂的催化效果。结果表明,该催化剂经多次使用,仍具有良好的催化性能。当催化剂用量为2g,酸与醇的摩尔比为2.61时,4次合成乙酸异戊酯产率平均达到70.6%,与相同条件下浓硫酸催化效果相当。
The catalyst of H_2SO_4 supported by silica gel was prepared and the catalyzing effect has been studied by esterification of acetic acid and isopentyl alcohol. It was found that the new catalyst has still better catalytic activity after utilized repeatedly. The reaction conditions are that the catalyst is 2.0 g, the mole ratio of acid to alcohol is 2.6︰1, the average esterification yield of isoamyl acetate is 70.6%.
