Abstract: Processes for the electrolysis of alkali halides employing dismantleable bipolar electrodes are provided of which the anodically active portion comprises titanium or other filmforming metal or alloy of similar anodic properties covered with a conducting layer, and of which the cathodically active portion comprises a common metal such as mild steel. Said electrodes are characterized by the separation in space of said active portions, at least one of which is apertured or foraminous, and by the electrical connection between said portions, which is achieved by means of two series of parts, each of said series being mechanically and electrically secured to one of said portions, the corresponding parts of each series being of shapes such that once connected in order to form pairs of parts, said pairs have a sealed cavity for housing a device or means for establishing electrical contact between the two parts of each pair. These electrodes are particularly suited for being mounted in cells of the filter-press type, for the electrolysis of brines.
