1-Naphthylamine-7-sulfonic acid C화학적 특성, 용도, 생산
화학적 성질
Brown crystalline. 1-Aminonaphthalene-7-sulfonic acid [119- 28-8]. (8-aminonaphthalene-2-sulfonic acid), 1,7-Cleve’s acid, C10H9NO3S, Mr 223.24, is 0.5 % soluble in water at 25℃ and 3 % soluble at 100 ℃. The sodium, potassium, calcium, and magnesium salts are readily soluble in water but the barium salt is only sparingly soluble. Sulfonation with oleum at 50℃ gives 1- aminonaphthalene-4,7-disulfonic acid. Alkali fusion gives 8-amino-2-naphthol, and Bucherer-type hydrolysis gives 1-hydroxynaphthalene-7-sulfonic acid.용도
