Description:Octadecy trimethyl ammonium bromide is white or light yellow solid (paste). The freezing point was 32℃, and the HLB value was 15.8. Soluble in water, good stability, heat resistance, light resistance, strong acid, strong alkali resistance, microbial degradation.
First, add dimethyl octadecylamine into the pressure kettle, and then add appropriate amount of water and isopropanol as solvent, with a small amount of alkali as catalyst. Air in nitrogen-filled replacement kettle (avoid side reactions), heated to 120 ~ 150℃, slowly pass bromomethane (theoretical amount). Reaction at 0.4-0.5mpa for 2 h, cooling, pressure reduction, water dilution to 50%. Discharging packaging which get Octadecy trimethyl ammonium bromide.
Octadecy trimethyl ammonium bromide used in catalyst, emulsifying agent, disinfectant, antiseptic, antistatic agent, etc.
Melting point:250 ºC (dec.)
Chemical property:White crystal powder.Soluble in water.
Use:Used as surface active agent.
