Procedure

Firstly, 41.5 g (0.17 moL) of triethoxysilylpropyl chloride (Tokyo Kasei Kogyo Co., Ltd.), 44.6 g (0.150 moL) of N,N-dimethyl octadecylamine (Tokyo Kasei Kogyo Co., Ltd.) and 40.5 g of ethanol are fed into a nitrogen-purged pressurized reactor and heated to 135° C. After the reaction for 20 hours, 121.4 g of dimethyloctadecyl[3-(triethoxysilyl)propyl]ammonium chloride (EtAC) in ethanol solution is obtained.
