Title:
CONTINUOUS PRODUCTION METHOD FOR BIQUATERNARY AMMONIUM SALT
Document Type and Number:
WIPO Patent Application WO/2021/088456
Kind Code:
A1
Abstract:
The invention uses a production method of first generating a monoquaternary ammonium salt intermediate, and then generating a target biquaternary ammonium salt product. The whole production process achieves continuous production of continuous feeding, continuous mixing, continuous reaction, and continuous discharging mainly by means of a static mixer and a continuous reactor. The production method provided by the present invention is simple and easy to operate, various biquaternary ammonium salts can be synthesized, and the equipment utilization rate is greatly increased by means of the continuous production method so as to shorten the production period. The use and the recycling treatment of organic solvents are avoided in the production process, no three wastes are generated in the whole process, and the method is environment-friendly.
