Abstract

processo de produção de clorato de metal alcalino. a presente invenção refere-se a um processo de produção de clorato de metal alcalino em uma célula eletrolítica com um único compartimento, que evita a necessidade de adição de dicromato de sódio ao processo, no qual reações colaterais indesejadas são reduzidas pelo uso de um cátodo que possui uma camada superior eletrocatalítica sobre um substrato que opcionalmente também possui uma ou mais camadas intermediárias. a camada eletrocatalítica superior compreende óxido de manganês e/ou cério.
