Abstract
An electrolytic cell is provided which is particularly suitable for the production of oxy-halogen compounds such as sodium chlorate by the electrolysis of an alkali metal halide such as sodium chloride. A removable casing divides the cell into a separate cell chamber and a cooling and concentration chamber outside of said casing; means are provided for the circulation of the electrolytic solution between the cooling and concentration chamber and the cell chamber, but there is a substantial seal against the passage of gas from one to the other. Gas such as hydrogen is separately removed from the interior of the casing, a gas sweep is provided across the surface of the electrolyte in the cooling and concentration chamber to cool the electrolyte and evaporate part of it so as to concentrate it. In accordance with this invention, such can be accomplished without danger of explosion. The removable casing achieves the desired separation into the cell chamber and cooling and concentration chamber while not restricting convenient access to the cells.
