新型咪唑啉两性表面活性剂的合成及性能测定

Syntheses of a novel imidazoline amphoteric surfactant and determination of properties

以油酸、N- (2 -羟乙基 )乙二胺和氨基磺酸为原料 ,经环化、硫酸化合成了咪唑啉硫酸酯盐型两性表面活性剂 ,对其表面张力、临界胶束浓度和泡沫性能等作了测定。认为将其用于山羊服装革的加脂剂中 ,可使皮革丰满、柔软、有弹性 ,具有良好的加脂效果。

A new imidazoline amphoteric surfactant was prepared from oleic acid, N-(2-hydroxyethyl) ethylene diamine and aminosulfonic acid via amidation ,cyclization and sulphation. Its surface tension, C cmc ,foaming capability etc. were measured. When it was applied to leather fatliquor for goat garment leather the results were good. For example,the leather was soft, plump and elastic.
