Process for the preparation of 2-arylbenzotriazoles |
| abstract |
Process for the preparation of 2- (2'-hydroxyphenyl) benzotriazoles of the formula from 2-nitro-2'-hydroxyazobenzenes of the formula characterized in that a 2-nitro-2'-hydroxyazobenzene compound is reduced in a strongly basic medium in the presence of an aromatic didydroxy or dioxo compound as catalyst and an alcohol with more than one carbon atom. The 2- (2'-hydroxyphenyl) benzotriazole compounds are known stabilizers for organic materials. |
