Abstract

Le procédé selon l'invention comporte l'électrolyse d'une solution de chlorure de sodium dans une cellule électrolytique sans diaphragme comportant au moins une cellule élémentaire 4 dans laquelle le rapport de la superficie utile de l'anode à la superficie utile de la cathode est au moins de 1,5/1. Suivant un mode de mise en oeuvre avantageux, des concentrations supérieures d'hypochlorite de sodium sont obtenues en effectuant l'électrolyse avec refroidissement de la solution d'électrolyte à environ 50 degrés C ou moins. Le refroidissement peut être assuré par un dispositif de refroidissement 3 situé entre des cellules élémentaires 4 ou bien pouvant être incorporé dans une ou plusieurs cellules élémentaires.
