Abstract

659,565. Electrolysis of alkali-metal salts. NAAMLOOZE VENNOOTSCHAP ONDERZOEKINGSINSTITUUT RESEARCH. Nov. 10, 1949, No. 28879. Convention date, Dec. 27, 1948. [Class 41] In the electrolysis of alkali-metal salts, using a mercury cathode, the mercury runs over an inclined substantially flat base which is parallel with an inclined anode and a diaphragm, the inclination with respect to the horizontal being between 1/ 50 and <SP>1</SP>/ 5 , and preferably being <SP>1</SP>/ 10 . As shown, a slightly-inclined rectangular iron base 1 is provided with a supply pipe 2 and a discharge pipe 3 for mercury 4. Longitudinal strips of insulating material support a diaphragm 5 which may consist of a fabric impregnated with rubber latex. Above the diaphragm is a perforated lead anode 6. A collecting tank 8 is connected to the base 1 by screws. The electrolyte may be supplied through an inlet 12 and discharged through an outlet 10. Part of the electrolyte may also be discharged through an outlet 11 beneath the diaphragm. Alternatively the electrolyte may be introduced through the opening 13, and discharged wholly or partly through the outlet 10. The base 1 may be formed with grooves at right angles to the flow of mercury to facilitate distribution thereof. Specification 471,912 and German Specification 701,771 are referred to.
