Synthesis and Properties of Novel Carboxylate Gemini Surfactant

Abstract:

The novel anionic gemini surfactant, isodium salt of N, N’, N”- trilauroyl-diethylenetriamine diacetate(TDAD), was synthesized with ethylenediamine, sodium chloroacetate and lauroyl chloride by displacement reaction and acylation reaction. The results show that TDAD has fairly low critical micelle concentration (cmc) and high surface activity. The adsorption isotherm of TDAD at the interface of oil sand/aqueous solution is taken on “S” model, and the adsorption loss of TDAD is much lower than that of the traditional monomer sodium laurate (SL).
