摘　　要：以高级脂肪醇、环氧氯丙烷、二甲胺和磷酸二氢钠为原料,合成了一类新型的磷酸酯甜菜碱两性表面活性剂3 [N (3 烷氧基 2 羟基丙基) N,N 二甲基铵] 2 羟基丙基酸性磷酸酯甜菜碱(简称AHDHPB),并通过红外光谱对其结构进行了分析,测定了表面活性。研究了AHDHPB 12和阴离子表面活性剂(AS)复配体系的降低表面张力能力、降低表面张力效率的增效作用。结果表明,合成的两性表面活性剂AHDHPB结构独特,具有较高活性和复配性能。A series of new amphoteric surfactants, 3-[N-(3-alkoxyl-2-hydroxypropyl)-N,N-dimethylammonium]-2-hydroxypropyl acid phosphobetaines(AHDHPB), were synthesized by using long chain fatty alcohol, epichorohydrin, dimethylamine and sodium dihydrogen phosphate as raw materials. The structure of the products was analyzed by IR spectroscopy. The surface activities were determined. By the interaction of the amphoteric surfactants AHDHPB-12 with anionic surfactants(AS), the efficiency and the ability of reducing surface tension were investigated. The results showed that the amphoteric surfactants have special structure, excellent surface activities and good compatibility.
