4-Amino-1-naphthol hydrochloride Use and Manufacturing
It is made from 1-naphthol and aniline as raw materials. Firstly, 1-naphthol and sodium hydroxide solution are reacted to prepare 1-naphthol sodium solution; aniline and sodium nitrite are reacted to make diazonium salt solution. The two are reacted below 10°C to obtain 4-phenylazo-1-naphthol. Then it is reduced and salted with hydrochloric acid to obtain 4-amino-1-naphthol hydrochloride.
