Reaction Steps
It is known that 1-amino-naphthalene-7-sulphonic acid can be prepared, for example, by sulphonating naphthalene, nitrating the resulting 2-naphthalenesulphonic acid and subsequently reducing this with iron (Beilstein H XIV, 765 and Ullmann, volume 12, 625 (1960)). 1-Amino-naphthalene-6-sulphonic acid is always formed as a by-product in this preparation and must be separated off.
