    摘要: This invention relates to an apparatus for the electrolytic treatment of alkali halide solution in a three chamber type electrolytic bath assembly comprising an anodic chamber, an intermediate chamber and a cathodic chamber arranged one after another in series. Each chamber is from its neighboring chamber by means of a cationic permselective membrane. The apparatus is characterized, according to this invention, in that the first one of the membranes separating the intermediate and anodic chambers is made of a fluorine-containing resin, while the second membrane separating the intermediate and cathodic chambers includes, as its main ion exchange radial, a pendant type phenolic radical or derivative thereof. The inventive process, which utilizes the above-described apparatus is characterized in that it utilizes a caustic alkali concentration in the intermediate chamber which ranges from about 10-20 wt.% while the output caustic alkali developed at and delivered from the cathodic chamber amounts to a concentration ranging from about 30 to 50 wt.%.
