I. Attorney, Agent or FirmAbstractImproved apparatus and process to electrolytically produce chlorine gas and an alkali metal hydroxide in a diaphragm cell. The improved process comprises employing a cation exchange diaphragm and contacting a foraminous cathode with an oxidizing gas having a regulatably controlled moisture content, while substantially simultaneously regulating the anolyte and catholyte compositions. The catholyte upper surface level is kept at a higher level than the anolyte upper surface. |
