Application and synthesis method of Cetrimonium Chloride

                            Application and synthesis method of Cetrimonium Chloride

chemical property：

Cetrimonium Chloride is a white or slightly yellow paste or solid. Relative density 0.968. Heat resistant, light resistant, and resistant to strong acids and alkalis. Has excellent stability and biodegradability. It has good compatibility with cationic, non-ionic, and zwitterionic surfactants. Refractive index nD201.377 8.

Application：

1.It is a cationic surfactant, which is widely used in asphalt emulsification and waterproof coating emulsification, glass fiber softening processing, industrial auxiliaries and silicone oil emulsifiers, pharmaceutical industrial auxiliaries, hair conditioner cosmetics emulsification conditioning, textile leather chemical additives, lotion foaming agent, fabric fiber softening and anti-static, polyester silk auxiliaries, organic bentonite covering agent, protein flocculation and water treatment flocculation, silkworm disinfectants, washing, disinfection and sterilization, etc.

2.Used for shampoo, hair care products, building coatings, fabric softeners, etc; This product is used as an emulsifier for emulsifying silicone oil, hair conditioners, fiber softeners, and anti-static agents. Can be used to soften and isolate paper. Used as a corrosion inhibitor in the pickling industry. The petroleum industry is used to prevent internal corrosion of pipelines and acid water treatment systems.

3.Anionic surfactants.

Production method：

Add 250 kg of hexadecanedimethylamine into the reaction vessel. Dissolve in 250L of petroleum ether. Inject 47 kg of methyl chloride. Stir and heat under sealed conditions, and azeotrope at 80 ℃ for 1 hour. Cooling, cooling, and depressurization were carried out, followed by recrystallization with a mixture of ethanol and ethyl ester at atmospheric pressure to obtain cetuximam chloride.
