Beschreibung

4-Hydroxy-7-methylamino-2-naphthalenesulfonic acid is used as a diazo dye in the textile industry. This compound is used to produce diazotization and then cyanuric chloride by the reaction of 4-hydroxy-7-methylamino-2-naphthalenesulfonic acid with sodium nitrite and hydrochloric acid. The condensate from this reaction is dissolved in an alkaline solution, which reacts with sodium bicarbonate to produce a reactive physicochemical substance that can be used for dyeing fabrics.
