Abstract

Sodium N,N'-dioctyl-ethylenediamine diacyl propionate, an anionic gemini surfactant, was synthesized by
ethylenediamine with n-octyl bromide, followed by reaction with succinic anhydride, cesium hydroxide and
triethylamine as catalyst, through N-alkylation and N-acylation. Structure of the intermediate and final product was
characterized by infrared spectrometer and nuclear magnetic resonance apparatus. The influences of material ratio and
reaction time on the N-alkylation product yield were investigated. Experimental results showed that the yield of the
N-alkylation product reached up to 64% under the optimum reaction conditions, the yield of the N-acylation product
was 39%.
