2-NAPHTHYLAMINE-8-SULFONIC ACID Chemical Properties,Usage,Production
Description
2-Aminonaphthalene-8-sulfonic acid [86- 60-2]. (7-aminonaphthalene-1-sulfonic acid), Badische acid, C10H9NO3S, Mr 223.24, crystallizes from water as needles or prisms although only 0.5 % soluble at 100 ℃. Alkalimetal salts are quite soluble in water. Caustic fusion yields 7-amino-1-naphthol, sulfonation in the cold with 20 % oleum gives 2-aminonaphthalene-6,8-disulfonic acid, but nitration gives a mixture of products. 2-Aminonaphthalene-8-sulfonic acid reacts with diazo compounds to form diazoamino compounds rather than coupling to give azo derivatives.
Chemical Properties
Colorless needles, partially soluble in water and alkalies, slightly soluble in alcohol.
Uses
Azo dye intermediate.
Production Methods
2-Hydroxynaphthalene-8-sulfonic acid is aminated by a Bucherer reaction under conditions similar to those used for Tobias acid.
