METHOD FOR PROCESSING ?-SULPHATOETHYLSULPHONYLANILINE-2-SULPHONIC ACID

The invention relates to a method for processing ?-sulphatoethylsulphonylaniline-2-sulphonic acid which is present as a solution in an aqueous sulphuric acid. In a first step, the ?-sulphatoethylsulphonylaniline-2-sulphonic acid is precipitated, separated and dissolved in water by adding (earth)alkali and/or ammonium salts, or the sulphuric acid is precipitated by adding calcium salts, the calcium sulphate thus arising is optionally separated, and in a second step, the solution thus arising is adjusted to a pH value of between 1 and 5 by adding (earth)alkali or ammonium hydroxide, carbonate, hydrogen carbonate and/or acetate, the existing calcium sulphate is separated, and the ?-sulphatoethylsulphonylaniline-2-sulphonic acid is isolated from the solution and the thus produced ?-sulphatoethylsulphonylaniline-2-sulphonic acid.
