摘要
以氧化锆负载硫酸为催化剂,对甘油乙酸反应体系进行研究.分别研究了催化剂用量和反应时间及原料的摩尔比对三醋酸甘油酯的产率的影响,实验结果表明:反应9小时,催化剂用量为丙三醇的质量的5wt%,n(丙三醇)/n(乙酸)=1:8,三醋酸甘油酯的产率达93.4%.
The reaction between glycerin and acetic acid using zirconium loaded by sulfuric acid as catalyst is studied, the study shows that zirconium catalyst is the best catalyst from the experiment result. Amount of catalyst, reaction time and mole ratio of reaction materials were investigated in the experiment. As optimum conditions is shown in the experiment： the reaction time 9 h, the amount of catalyst for the quality of glycerol 5 wt%, n （glycerin） / n （acetic acid） = 1：8, the yield of triacetin amount to 93.4%.
