报道了以甘油和醋酸为原料 ,用固定化催化剂催化合成三醋酸甘油酯 .实验表明 :固定化催化剂活性高、可以重复使用多次 ,三醋酸甘油酯收率可达 92 %以上 . It was reported that glycerol and acetic acid were used as raw materials to catalyze the synthesis of triacetin with immobilized catalyst.The experimental results show that the immobilized catalyst has high activity and can be reused many times and the yield of triacetin can reach more than 92%.
