标题:Process for the preparation of 1-amine-2-naphthol-4-sulfonic acid
发明人：ALBRECHT BERNHARD; BEYRICH JUERGEN
权利人:CIBA GEIGY CORP
摘要:There is disclosed an improved semi-continuous and continuous process for the preparation of 1-amino-2-naphthol-4-sulfonic acid by nitrosation of 2-naphthol, addition of bisulfite, acidification with mineral acid and reduction of the reaction product so obtained, which comprises charging the reactor with the nitrosating agent and simultaneously adding 2-naphthol and mineral acid simultaneously in separate streams in the semi-continuous process, or charging the reactor with the reaction mass and simultaneously adding 2-naphthol, mineral acid and the nitrosating agent in separate streams in the continuous process. The product can be further used, without isolation, for the synthesis of dyes.
