Abstract
1356000 Amino-benzene- or amino-naphthalene sulphonic acids BADISCHE ANILIN- & SODA-FABRIK AG 7 Oct 1971 [9 Oct 1970] 46668/71 Heading C2C Unsubstituted or substituted aminobenzenesulphonic acids or aminonaphthalenesulphonic acids are obtained by treating the appropriate phenylamine sulphate or naphthylamine sulphate, in the form of a melt or solution, with or without the addition of water, in a state of fine dispersion in a fluidized bed of the required aminobenzenesulphonic acid or aminonaphthalenesulphonic acid, with a hot inert gas. An example is given for the preparation of sulphanilic acid.
