ABSTRACT:
A method of preparing halo-benzotriazoles is disclosed. The method involves mixing an aqueous solution of sodium hypohalite with an aqueous slurry or suspension of a benzotriazole. Preferred sodium hypohalites are sodium hypochlorite or sodium hypobromite and the preferred benzotriazole is tolyltriazole.
