Product description:This product is white or light yellow solid (paste). Freezing point 32 ℃, HLB value of 15.8. Soluble in water, good stability, heat resistance, light resistance, resistance to strong acid, strong alkali, microbial degradation.First turn on the dimethyl octadecylamine add to the pressure kettle, add right amount water and isopropyl alcohol as solvent, with a small amount of alkali as the catalyst. Nitrogen replacement in air (to avoid side effects), heating to 120 ~ 150 ℃, slowly into the methyl bromide (theory). Reaction for 2 h under 0.4 ~ 0.5 MPa, cooling, step-down, diluted to 50%. Discharging the packing is finished.Used in catalyst, emulsifier, disinfectant, antiseptic, antistatic agent, etc.
