Abstract

PROCESSO PARA O PROCESSAMENTO DO áCIDO BETASULFATOETILSULFONILANILINA-2-SULFÈNICO PARTINDO DE UMA SOLUçãO EM áCIDO SULFúRICO AQUOSO. Método para o processamento do ácido <225>-sulfatoetilsulfonilanilina-2-sulfónico partindo de uma solução em ácido sulfúrico aquoso, que compreende uma primeira etapa do ácido <225>-sulfatoetilsulfonilanilina-2-sulfónico sendo precipitado através da adição de sais de metais alcalinos ou alcalinos terrosos e/ou de amónio, separado e dissolvido ou o ácido sulfúrico sendo precipitado através da adição de sais de cálcio e o sulfato de cálcio resultante sendo separado, se apropriado e uma segunda etapa da solução resultante sendo ajustada em um pH entre 1 e 5 através da adição de hidróxido, carbonato, bicarbonato e/ou acetato de metais alcalinos ou alcalinos terrosos ou de armónio, qualquer sulfato de cálcio ainda presente sendo separado e o ácido <225>-sulfatoetilsulfonilanilina-2-sulfónico sendo isolado da solução.
