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

Epoxypropyl dodecyl dimethyl ammonium chloride (EPDDMAC) was synthesized withN,N-dimethyl dodecyl amine (DMDA) and epichlorohydrin (EPIC). Diethyl-2,3-epoxypropyl-[3-methyldimethoxyl)] silpropyl ammonium chloride (DEEPSAC) was synthesized withN,N-diethyl-aminopropyl-methyldimethoxysilane (DEAPMDES) and epichlorohydrin (EPIC). The products were characterized by infrared and elemental analysis and1H NMR spectroscopy. The surface tension, conductivity, and antibacterial activities of EPDDMAC and DEEPSAC were studied.
