Put octadecyl tertiary amine into the pressure kettle, add an appropriate amount of isopropanol and not as the reaction medium, and then add a small amount of sodium hydroxide as the catalyst. Replace the air in the kettle with nitrogen and raise the temperature to 50 ℃. Add 1% (mass) of methyl chloride in excess of the theoretical amount. Close the pressure kettle. React at 0.5MPa for 4H. The reaction is over. After desalination treatment, dilute it with water to the required concentration. The finished product is discharged and canned.
