十八烷基二甲基三甲硅丙基氯化铵 - Reference Information

LogP	4.9
EPA chemical information	Information provided by: ofmpub.epa.gov (external link)
Use	Dimethyldecadecyl [3-(trimethoxysilyl) propyl] ammonium chloride is a silicone quaternary ammonium salt. Quaternary ammonium salt can absorb bacteria with negative charge and has good bactericidal effect. Dimethyldecadecyl [3-(trimethoxysilyl) propyl] ammonium chloride can be used in cotton, nylon, polyester and other fiber products processing, has a wide range of uses. Recently, it has also been used in non-woven fabrics, foamed polyurethane, synthetic leather and other materials.
preparation	1) weigh γ-chloropropyl trimethoxysilane (2.782kg, 14 mol) and add it to the 150 liter reactor with condensation and reflux device. after the reactor is sealed, the reactor heating mechanism is opened, and the reactor is heated to 40-50 ℃ at a stirring speed of 40-80 r/min, start to drop decadecyl dimethyl tertiary amine (2.976kg, 10 mol) into the reaction kettle for 3 hours; when the temperature is raised to 140 ℃, keep a constant temperature, and react in a closed and mixed solvent reflux state for 36 hours to obtain a silicone quaternary ammonium salt product solution. When the conversion rate of silicone quaternary ammonium salt is determined to be 93% by nuclear magnetic resonance method, the reaction heating is stopped; 2) When the solution in the reaction kettle drops to normal temperature, use hydrochloric acid to adjust the pH of organic silicon quaternary ammonium salt in the kettle to 5.5-6.5, stir homogenously for 5-10min, then filter and decolorize with 600-800 mesh diatomite to remove impurities to obtain dimethyldecadecyl [3-(trimethoxysilyl) propyl] ammonium chloride.
