White is a pale yellow solid or colloidal liquid. Soluble in water (10 water), ethanol, acetone-soluble, almost insoluble in ether and benzene. Heat-resistant, light-resistant, strong solution-resistant and strong alkali-resistant. It has excellent surface activity, stability and biodegradability.
Firstly, decanol and bromine were reacted under the catalysis of red phosphorus to obtain Bromo-decane, and then reacted with trimethylamine quaternary ammonium.
in the water treatment industry, it can be used as a bactericidal algaecide, slime stripping agent and cleaning agent, and has a good emulsifying effect on a variety of oils in water. It has good compatibility with cationic, nonionic and zwitterionic surfactants. Its anti-microbial performance is equivalent to that of benzalkonium chloride. It can be used for microbial control and cleaning of circulating water system, and has a good killing effect on heterotrophic bacteria, iron bacteria and sulfate reducing bacteria. In general, it is used at a concentration of 50 to 100mg/L.
mice and rats were intravenously injected with LD50:32, 0 mg/kg, 44.0 mg/kg. It is corrosive to skin and eyes.
