4-Chloro-2(3H)-benzothiazolone Use and Manufacturing
The preparation method is to put 2-amino-4-chlorobenzothiazole hydrobromide, dichloroethane, hydrochloric acid and water into the reaction kettle, stir, the temperature is 15-20 ℃, dropwise add sodium nitrite solution, add After the completion of stirring, continue to stir for 3 hours, pre-set the layering, the oil layer is desolventized and distilled out of dichloroethane, add ethanol while hot, and add 30% hydrochloric acid and sulfuric acid uniformly. After the addition, the reaction is refluxed for 3 hours, and the reaction is over. The product is obtained by cooling, filtering and drying.
4-chlorobenzothiazolone is an intermediate of the herbicide herbicide.
