Abstract

Procedimiento para el tratamiento de ácido 4-β-sulfatoetilsulfonilanilin-2-sulfónico, que se encuentra como solución en ácido sulfúrico acuoso, caracterizado porque en una primera etapa se precipita el ácido 4-β-sulfatoetilsulfonilanilin-2-sulfónico mediante adición de sales de metal alcalino o alcalinotérreo y/o sales de amonio, se separa y se disuelve en agua, o se precipita el ácido sulfúrico mediante adición de sales de calcio, se separa dado el caso el sulfato de calcio generado, y en una segunda etapa se ajusta la solución generada mediante adición de hidróxido, carbonato, hidrogenocarbonato y/o acetato de metal alcalino o alcalinotérreo o de amonio a un valor de pH entre 1 y 5, se separa el sulfato de calcio aún presente, y se aísla el ácido 4-β-sulfatoetilsulfonilanilin-2-sulfónico a partir de la solución.
