Abstract
<B>MéTODO PARA FAZER ELETRóLISE EM UMA SALMOURA<D>. A invenção refere-se a um método para fazer eletrólise em uma solução de cloreto de sódio por meio de uma célula de eletrólise tendo uma membrana e um catódio de redução de oxigênio. Este método consiste em fazer eletrólise de uma solução aquosa de cloreto de sódio por meio de uma célula compreendendo uma membrana de permuta de cátion que divide a célula em um compartimento de anódio e um compartimento de catódio no qual o referido catódio é colocado diretamente contra a membrana de permuta de cátion, o referido compartimento de cátion sendo fornecido com um gás umedecido contendo oxigênio, caracterizado pelo fato de que, para se obter uma concentração em peso de hidróxido de sódio entre a membrana de permuta de cátion e o catódio menor do que 38,8%, faz-se uso de uma solução aquosa de cloreto de sódio (anólito) tendo uma concentração em peso de cloreto de sódio menor do que 200 g/l, e em que a água umedecendo o gás contendo oxigênio tem a forma de vapor de água.
