摘要
以氢化松香和甘油为原料、氧化锌为催化剂,进行氢化松香甘油酯的合成反应研究。采用单纯型搜索法优化合成氢化松香甘油酯的反应条件,以水平平均法考察了甘油用量、反应温度、催化剂量和反应时间四个因素对酯化率的影响。实验结果表明,反应的最佳工艺条件是:甘油用量8.9g,反应温度270℃,催化剂量0.09g,反应时间2.39h;对酯化反应影响最大的因素是催化剂用量,其次是反应时间和甘油加入量,反应温度的影响最小。
The synthesis of hydrogenated rosin glycerin ester with ZnO catalyst was studied, using hydrogenated rosin and glycerin as raw materials. The technological conditions of synthesizing hydrogenated rosin glycerin ester were optimized by simplex search method. Optimum technological conditions were attained as follows： the amounts of glycerin 8.9g, reaction temperature 270℃, the amounts of catalyst 0.09g, reaction time 2.39h. The results showed that the most significant factor which influence esterification was the amounts of catalyst, and the follows reaction time and the amounts of glycerin were the less, and reaction temperature was the least.
