| Abstract: | Objective O-decanoxylbenzoic o-phenyl azobenzene ester was synthesized by the diazotization reaction,coupling reaction,esterification reaction and Williamson reaction.Methods O-phenolylazobenzene was synthesized from the diazotization salt prepared from aniline and xenol by coupling reaction,and o-decanoxylbenzoic o-phenyl azobenzene ester was synthesized from the o-phenolylazobenzene and the p-hydroxybenzoic acid using dicyclohexylcarbodiimide as a dewater regent and 4-dimethylaminopyridine as a catalyst.A... |
