Abstract
Procédé d'électrolyse d'une solution aqueuse de chlorure de métal alcalin. Il consiste à électrolyser ladite solution en maintenant la température de la liqueur aqueuse d'hydroxyde de métal alcalin présente dans le compartiment cathodique à une valeur plus faible de 1 à 30 degrés C à température de la solution de chlorure de métal alcalin présente dans le compartiment anodique et en utilisant une cellule électrolytique divisée par une membrane échangeuse de cations en un compartiment anodique et un compartiment cathodique. Amélioration de l'efficacité de courant sans effet fâcheux sur la tension, ce qui permet un fonctionnement de longue durée avec une faible consommation d'énergie électrique et aussi l'obtention d'un hydroxyde de métal alcalin ne contenant qu'une quantité réduite d'ion chlorure.
