Abstract

Abstract Recent studies have shown that the surfactants bearing an ultra-long hydrophobic chain (> C18) exhibit unique self-assembly properties. However, their synthesis and surface activities have been less documented. In this work, monounsaturated alkyl dimethyl amidopropyl betaines, UCnDAB (n= 18, 22, and 24), were prepared by the reaction of the corresponding fatty acids with N, N-dimethyl-1, 3-propanediamine, followed by ...
