Novel Synthesized Cationic Gemini Surfactants Bearing Amido Group and Their Application in Nanotechonoly

Abstract

A nonionic modified cationic gemini surfactants (MEGS, PEGS, SEGS and OEGS) were synthesized via Chloroacetic acid was taken to react with ethylene glycol compound in the presence p-Toluene sulfonic acid as acid catalyst and dry benzene as a required solvent to form the diester compound. Secondly, A various fatty acids as myristic, palmitic, stearic and oleic acids were reacted with 3-(N, N Dimethylamino)-1-propylamine in the presence a dry benzene as a solvent to form the corresponding fatty acid amides (MA, PA, SA, OA). Finally, the quaternarization process was done by treatment of the prepared diester compound and the obtained fatty acid amides (MA, PA, SA, OA) in ethanol as a solvent to produce the corresponding cationic gemini surfactants (MEGS, PEGS, SEGS and OEGS). The chemical structures of the synthesized Gemini surfactants were elucidated by FTIR and 1 HNMR spectroscopic tools. The evaluation of surface and thermodynamic properties was studied, leading to conclude the potential ability of the synthesized surfactants to be adsorbed in solutions which means the applicability in a wide range industrial field.
