製造方法
Synthesis of benzyldimethylstearylammonium chloride: put 450kg of dimethyl octadecylamine into the reaction kettle, heat to 80~85℃, and slowly add 180kg of benzyl chloride under stirring in 1.5~2h. Keep warm at 80～90℃ during the drop addition. After the dosing is completed, increase the temperature to 100~105℃, hold the reaction for several hours and take samples to measure the pH value. When the pH value of 1% aqueous solution reaches 6~6.5, the reaction is completed. Cool down to 60℃ and discharge to get benzyldimethylstearylammonium chloride.
