LogP	3.61 at 25℃
performance	decyltrimethylammonium chloride has good compatibility with cationic, nonionic and amphoteric surfactants, and has excellent permeability, softness, emulsification, antistatic, biodegradability and bactericidal properties.
application	decyl trimethyl ammonium chloride has good chemical stability and is widely used in hair conditioners, fabric softeners, fiber antistatic agents, silicone oil emulsifiers, asphalt emulsifiers, organobentonite modifiers, disinfectants and fungicides, protein flocculants in the biopharmaceutical industry and water treatment flocculants.
use	this product is used as antistatic agent for textile fibers, hair conditioner, emulsifier for asphalt, rubber and silicone oil. And widely used in disinfection and fungicide. Used as a fabric softener to make the fiber bulky and soft. It is used as a raw material for asphalt emulsification and conditioner Cationic surfactant, widely used in asphalt emulsification and waterproof coating emulsification, silicone oil emulsification, hair conditioner cosmetic emulsification conditioning, fabric fiber soft and antistatic, organobentonite modification, protein flocculation and water treatment flocculation in the biopharmaceutical industry, glass fiber soft processing, anti-burning treatment agent for nylon parachute surface, as well as fungicides and disinfectants, etc.
production method	pass eighty tertiary amine into the pressure kettle, add appropriate amount of isopropanol and no reaction medium, and then add a small amount of sodium hydroxide as catalyst. After replacing the air in the kettle with nitrogen, the temperature is raised to 50 ℃, and 1% (mass) more than the theoretical amount of methyl chloride is introduced. Closed pressure kettle. Reacts at 0.5 MPa for 4 hours. The reaction ends. After desalination treatment, dilute with water to the required concentration. The discharge can is the finished product.
