4-아미노나프탈렌-1,5-디술폰산 화학적 특성, 용도, 생산

• 화학적 성질

  1-Aminonaphthalene-4,8-disulfonic acid [117-55-5]. (4-aminonaphthalene-1,5- disulfonic acid), C10H9NO6S2, Mr 303.3, and its acid monosodium salt are sparingly soluble in cold water, but the disodium salt is readily soluble. Hydrolysis with sodium hydroxide at 200 ℃ yields 1-amino-8-hydroxynaphthalene-4-sulfonic acid; at higher temperature, 1,8-dihydroxynaphthalene-4-sulfonic acid is formed. Heating with bisulfite produces 1-hydroxynaphthalene4,8-disulfonic acid. Diazo compounds couple with 1-aminonaphthalene-4,8-disulfonic acid to form azo compounds, in contrast to 2-aminonaphthalene-4,8-disulfonic acid, which reacts to form diazoamino compounds.

• Safety Profile

  When heated to decomposition itemits toxic fumes of SOx and NOx.
