摘　　要：采用正交实验对影响乙二醇硬脂酸酯合成的因素做比较分析,实验发现,采用自制负载型催化剂,能够用较少的乙二醇量合成合格产品,较优的合成条件为：酸醇摩尔比1∶0.8,初始反应温度190℃,反应0.5 h后升温到220～230℃继续反应1h,催化剂用量0.6％,硬脂酸酯化率可达98.8％,物料收率99.2％.Orthogonal experiment is conducted to compare and analyze the factors effecting the compound of ethylene glycol stearate, the experiment result showed that self made supported catalyst was available to compound qualified products with less ethylene glycol, optimum synthesis conditions were： acid alcohol mole ratio 1：0.8, the initial reaction temperature 190 ℃, react 0.5 h, the reaction temperature was raised to 220 ～ 230 ℃ continue to react lh, the amount of catalyst 0.6 % reaching a esterification rate of 98.8 % for stearic acid, and material yield rate of 99.2 %.
