Gemini Cationic Surfactant

In order to obtain some novel cationic surfactants with high surface activity, n-octadecyldimethylamine and epichlorohydrin were used to synthesize 2-hydroxy-1, 3-dis (chloride octadecyl dimethyl ammonium) propane, which was a kind of gemini quaternary ammonium salt. N-octadecyldimethylamine and epichlorohydrin were used to prepare active epoxy intermediate glycidyloctadecyldimethyl ammonium chlorided, and then glycidyloctadecyldimethyl ammonium chlorided was reacted with octadecyldimethyl amine hydrochloride to synthesize the gemini cationic surfactant. FTIR and 1H NMR were used to represent structure of the gemini cationic surfactant. The interface characteristics were studied in detail. The critical micellar concentration (CMC) was determined by surface tension test to obtain the values of CMC and surface tension at CMC. The foam ability and foam stability of the gemini cationic surfactant were also discussed through contrast octadecyltrimethyl ammonium chloride and cetyltrimethyl ammonium chloride.
