| titleOfInvention | A kind of production process for continuous preparation of glufosinate-ammonium |
| abstract | The invention discloses a production process for the continuous preparation of glufosinate-ammonium, which comprises mixing phosphazene liquid and hydrochloric acid and then sending it to a hydrolysis tower, and the low boiler obtained by hydrolysis is recovered by a condenser to obtain ethanol; the kettle liquid obtained by hydrolysis is sent to The hydrochloric acid flasher, the removed hydrochloric acid is sent to the hydrochloric acid absorber, the concentrated liquid is sent to the crystallization kettle, and the crystallized material of the crystallization kettle is sent to the centrifuge to obtain the crude glufosinate-ammonium, and the centrifugal mother liquor is returned to the hydrochloric acid flasher. The acid hydrolysis process that can be continuously produced by the method of the invention solves the drawbacks caused by the intermittent production of the acid hydrolysis reaction in the domestic Strecker method, and has the characteristics of short production time, high production efficiency, low environmental protection pressure, and low production cost. . |
