Synthesis and application exploration of novel gemini surfactant

A novel gemini surfactant dichloride- N,N,N′,N′-tetramethyl-N,N′-dicetyl-2-propanol-1,3-ammonium (DTDPA) with two hydrocarbon chains connected by hydroxyl spacer chain was synthesized by three steps reactions. The values that characterized the solution properties of gemini surfactant including critical micelle concentrations (cmc), γcmc, pC20 and cmc/C20 were measured. The results demonstrated that the gemini surfactant gave low cmc, great efficiency in lowering the surface tension and strong adsorption at air/water interface. The application of DTDPA in the field of enhanced oil-recovery (EOR) technology and suspension copolymerization was investigated. DTDPA can reduce the interfacial tension of crude oil-water system sharply and maintain the viscosity of surfactant-PAM system excellently. The addition of DTDPA as assistant dispersant system can promote the oil absorption capacity of resin prepared by suspension copolymerization method within a range of concentration and reduce the oil absorption balanced time as increasing concentration of gemini surfactant.
