| titleOfInvention | Method for producing 2- (2'-hydroxyphenyl) benzotriazoles |
| abstract | (57) [Summary] (Modified) PROBLEM TO BE SOLVED: To provide a method for producing 2- (2'-hydroxyphenyl) benzotriazoles in which the reaction is mild, the yield of the final product is high, and the by-products can be easily recovered. To do. SOLUTION: A 2-nitro-2'-hydroxyazobenzene derivative represented by the general formula (1) and an alcohol are heated in an alkaline aqueous solution mixed with a hydrophobic solvent in the presence of a redox catalyst and reacted by azeotropic distillation. 2- of the general formula (2), which comprises reacting while removing water in the system to the outside of the system. Process for producing (2'hydroxyphenyl) benzotriazoles. [However, R 1 represents a hydrogen or chlorine atom, R 2 represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms or an aralkyl group having 1 to 4 carbon atoms in the alkyl portion, and R 3 represents 1 to 12 carbon atoms. Represents an aralkyl group having 1 to 4 carbon atoms in the alkyl group or alkyl moiety. ] |
