摘　　要： 合成了新的非离子表面活性剂丙烯海松酸甘油酯聚氧乙烯醚,研究丙烯海松酸与甘油的部分酯化及甘油酯与环氧乙烷的加成反应。适宜的反应条件为:丙烯海松酸与甘油反应温度260-270℃,用料摩尔比为1:3,反应时间5 h,催化剂ZnO用量为酸质量的0.08％;甘油酯与环氧乙烷的加成反应催化剂为KOH,用量为酯质量的0.7％-0.8％,温度150℃。测定了产物的表面物理化学性能,研究了环氧乙烷聚合度对产物表面物理化学性能的影响。 Acrypimaric acid glycerol ester polyoxylethylene ether (RGEO), a kind of new nonionic surfactant, was synthesized, and the reactions, which include partial esterification of acrylpimaric acid with glycerol and the addition reaction of glycerol ester with epoxy ethane, were studied. The suitable reaction conditions were obtained as follows: the molecular ratio of acrypimaric acid to glycerol for esterification was 1 : 3 and they react at 260 - 270°C for 5 h with 0.08 % in catalyst ZnO's mass ratio (based on the mass of acid). The addition of ester with epoxy ethane is taken at 150°C with 0.7% - 0.8% of catalyst KOH's mass ratio (based on mass of glycerol ester). Surface physicochemical properties of the products were measured. The relationship between surface physicochemical properties of the products and polymerization degree of epoxy ethane was studied.
