A colorless or yellowish liquid, paste, or solid. Soluble in hot water and alcohols, 1% of the aqueous solution pH value of 6~8. Decasix alkyl trimethyl ammonium chloride is a cationic surfactant, which can be heat resistant, light resistant, light resistant, resistant to strong acids and strong bases, and has good surface activity, stability and biodegradability.
Under the catalysis of CuO/Cr2 03 system catalyst with silica gel as carrier, decasix alkyl dimethyl tertiary amine was synthesized from decasix alcohol and dimethylamine at a certain temperature and pressure. Decasix alkyl trimethyl ammonium chloride was prepared by using sodium hydroxide as catalyst and methyl chloride.
in petroleum, paper, food processing, textile and other industrial water treatment as a fungicide. Can be used for natural and synthetic fibers, plastics, paper and other industries of antistatic agents, leather softener, fiber softener, pigment finishing agent, asphalt and high temperature oil-in-water emulsion slurry emulsifier. Latex industry as anti-adhesion agents, organic synthesis of catalysts, metals and alloys of corrosion inhibitors. It can also be used as dispersant, coagulant aid, duckweed insecticide, etc. Good compatibility with cationic, nonionic and amphoteric surfactants.
It is irritating and corrosive to eyes. Rat oral LD50 250 mg/kg,300 mg/kg. Care was taken not to mix with the anionic surfactant.
