摘　　要：选用脂肪酸聚甘油为原料,合成出几种聚甘油酯,对其表面物理化学性能作了比较。并对聚甘油硬脂酸酯合成工艺进行优化,发现优化工艺后获得的聚甘油硬脂酸酯的性能较好,HLB值为8.5～9.8,表面张力为45～49mN/m,发泡力为18～20mm。最后取其中试产品与国内外知名产品的性能进行了比较,结果表明中试产品是一种性能优良的非离子表面活性剂,可作为乳化剂、破乳剂等使用。Several kinds of polyglycerol esters were synthesized by reaction of fatty acid with polyglycerol and their surface physicochemical properties were investigated. The result showed that, under the optimal synthesis conditions, best capabilities of polyglycerol ester of stearic acid were achieved with the values of HLB, surface tension and foaming power being of 8.5-9.8, 45-49mN/m, and 18-20 mm, respectively. It was also found that industrial-scale product was a good nonionic surfactant, which can be used as emulsifier, demulsifier, and corrosion inhibitor.
