Synthesis, Surface Properties, and Antibacterial Activity of Quaternary Ammonium Salts Containing Epoxide Group

Abstract Epoxypropyl dodecyl dimethyl ammonium chloride (EPDDMAC) was synthesized with N,N-dimethyl dodecyl amine (DMDA) and epichlorohydrin (EPIC). Diethyl-2,3-epoxypropyl-[3-methyldimethoxyl)] silpropyl ammonium chloride (DEEPSAC) was synthesized with N,N-diethyl-aminopropyl-methyldimethoxysilane (DEAPMDES) and epichlorohydrin (EPIC). The products were characterized by infrared and elemental analysis and 1H NMR spectroscopy. The surface tension, conductivity, and antibacterial activities of EPDDMAC and DEEPSAC were studied.
