SYNTHESIS AND CHARACTERIZATION OF CLEAVABLE CATIONIC SURFACTANTS WITH 1,3-DIOXANE RING

摘要

A series of cationic cleavable surfactants was prepared by condensation of 2-alkyl-1,3-propanediols with 3-bromopropanal, followed by reaction with triethylamine. Each surfactant is a mixture of two diastereomers, and their precursors' stereochemical assignments were based on H-1 nuclear magnetic resonance spectra and melting points. The critical micelle concentrations, Krafft points and destructibility of these surfactants were determined. [References: 24]
