摘要
用乙酸和正丁醇为原料，以不溶性杂多酸稀土盐为催化剂合成了乙酸丁酯。当催化剂用量为反应物总质量的３％ ， 反应温度为 １１０℃左右， 反应物料乙酸与正丁醇的摩尔比为 １２０∶１ 时， 其酯化反应只需 １５～２５ ｈ， 乙酸转化率可达 ９０％ 。
Catalyzed by insoluble rare earth salts of heteropoly acid,butyl acetate have been synthesized from butanol and acetic acid. When the catalyst quantity is 3% of total reaction mass,the mole ratio of acetic acid and butanol is 1 20∶1 and the temperature is approximately 110℃,the reaction time of esterification is only 1 5～2 5h, the conversion proportion may reach 90%.
