Methyl trioctyl ammonium chloride CAS 5137-55-3

Preparation of methyl trioctyl ammonium chloride cas:5137-55-3: Weigh 1000g of trioctyl amine and place it in a beaker. Add concentrated hydrochloric acid dropwise (total amount of HCl added is about 103g), stir magnetically, and after neutralization reaction, evaporate about 80% of the water using a constant temperature water bath, and then vacuum dry to obtain the product trioctyl ammonium chloride; Weigh 1000g of trioctylammonium chloride and 235g of dimethyl carbonate separately, and add them to a 10L reaction kettle in sequence. After blowing away the air inside the kettle with nitrogen gas, the reaction is carried out in a closed container at a reaction temperature of 170 ℃. After the reaction temperature reaches 170 ℃, stir for 8 hours; After the reaction is complete, about 1026g of methyl trioctyl ammonium chloride is obtained. Trioctyl methyl ammonium chloride is a yellow viscous liquid that can be used as an emulsifier, disinfectant, fungicide, antistatic agent, catalyst in antioxidants, metal extractant, Phase Transfer Catalyst, and surfactant. It can be used as a catalyst in 168 antioxidants instead of dimethylformamide (DMF).
