Imidazole, 4,5-diphenyl- (8CI) - Production method
It is obtained by the reaction of thio4, 5-diphenylimidazole with concentrated nitric acid. Thio4, 5-diphenylimidazole is dissolved in hot glacial acetic acid, the obtained solution is added to dilute nitric acid, boiled, and the fierce reaction emits yellow smoke. After cooling, the unreacted thio4, 5-diphenylimidazole is filtered out, and the filtrate is neutralized with sodium hydroxide solution to precipitate precipitation. Dissolve the precipitate in dilute hydrochloric acid, then filter, and neutralize the filtrate with ammonia to obtain 4,5-diphenylimidazole. 60% yield.
