Chemische Eigenschaften

1-Hydroxynaphthalene-4,8-disulfonic acid [117-56-6]. (4-hydroxynaphthalene-1,5- disulfonicacid),Schollkopf ’s acid, deltaacid, oxy Chicago acid, C10H8O7S2, Mr 304.3: the sodium saltis readily solubleinwater, butthe barium saltis only sparingly soluble.Cold5 % oleumdehydrates 1-Hydroxynaphthalene-4,8-disulfonic acid to the sultone, whereas with hot 25 % oleum it undergoes sulfonation to give 1-hydroxynaphthalene-2,4,8-trisulfonic acid. Amination (Bucherer) gives 1-aminonaphthalene-4,8-disulfonic acid and caustic fusion gives 1,8-dihydroxynaphthalene-4-sulfonic acid. Diazo coupling and nitrosation take place in the 2-position.
