Abstract

<B>REMOçãO DE SAIS DE SOLUçõES AQUOSAS DE SULFONAMIDAS<D>. Para remover os sais (em particular NH~ 4~Cl) presentes em uma solução aquosa de sulfonamida (em particular CH~ 3~SO~ 2~NH~ 2~), a solução é submetida a uma eletrodiálise de dois compartimentos. Por manter o pH em um valor abaixo de 7, evita-se a formação de amónia. A solução desmineralizada pode ser concentrada para recuperar, após cristalização, o sulfonamida.
