以丙烯酸和蔗糖为原料，由酯交换反应合成丙烯酸蔗糖酯（单，双），研究了乳化剂用量、催化剂种类、丙烯酸与蔗糖的摩尔比、阻聚剂种类、溶剂用量对收率的影响。实验结果表明，最佳合成条件是：用对甲苯磺酸作催化剂1.7 g，对甲氧基苯酚作为阻聚剂0.5 g，丙烯酸与蔗糖的摩尔比为2.5：1，分散剂水36 mL，硬酯酸钠为乳化剂4 g，在此条件下，总酯收率可达90％以上。

Sucrose acrylate ( single and double ) was synthesized by the ester exchange using sucrose and acrylic acid as the raw material.The influence of many factors on the synthesis , such as the emulsifier dosage , the type of catalyst , the molar ratio of acrylic acid and sugar , the type of inhibitor , the dosage of solvent , were researched.The experimental results showed that the best synthesis condition was as follows:p-toluenesulfonic acid as a catalyst was 1.7 g, p-methoxy phenol as a polymerization inhibitor was 0.5 g, acrylic acid and sucrose was 2.5:1 , the dispersant was 36 mL, sodium stearate as emulsifier was 4 g.In these conditions , the total ester yield was up to 90%.
