N－酰基二乙醇胺类表面活性剂的合成与去污效果评价

SYNTHESIS OF N-ACYLDIETHANOLAMIDE DETERGENTS AND EVALUATION OF THE EFFECT OF REMOVING FILTH

本文改进了直接合成法的工艺，并用此工艺合成了６个酰胺类化合物。以多肽酰胺和市售某干洗精为对照，测定了它们的去污值。结果证明，合成的产品中以Ｎ－十二酰基二乙醇胺的去污效果最好，它的使用浓度比市售某干洗精低５０倍，而且在硬水（０～５０德度）和酸性、硷性水中（ｐＨ４～１０）的去污值都好于市售某干洗精。

he compounds containing six acidamides were synthesized by the tech-nological process of direct synthesis which was modified slightly.Com-pared with polypeptideacidamide compounds and“Gan Xijing”,the lauroyldiethanol,one of the compounds synthesized exhibited great detergency.The concentration of the lauroyldiethanol used was 50 folds lower than that of“Gan Xijing”and the detergency was significantly higher in the water with various hardness(0～50 G. degree) and pH values(4～10).
