6-Amino-1-naphthalenesulfonic acid synthesis

12synthesis methods
Tobias acid is added to a mixture of sulfuric acid and oleum, and the reaction is completed by stirring for 12 h at 25℃. The resulting sulfonation mass, containing mainly 2-aminonaphthalene-1,5-disulfonic acid, is poured into water and heated at 105℃ for 3 h to desulfonate and precipitate the product which, after cooling, is filtered off; the yield is 95 %.
