Abstract
221,634. Shields, T., (Koholyt Akt.-Ges.). Aug. 22, 1923. Electrodes; preparing surfaces; alkali soaps, preparing. - Carbon or graphite electrodes are impregnated with an alkali soap to lengthen their life. The electrodes may be immersed in a soap solution in a vacuum, the pressure being subsequently raised to about 100 atmospheres. In another method the electrodes are impregnated with substances such as rape-seed oil, cocoa-nut oil or linseed oil, which are subsequently converted into soap within the pores of the electrodes. The electrodes may be immersed in linseed oil, for example, heated to 120‹ C. to expel air. The impregnated electrode is then made the anode or cathode in an electrolytic bath of caustic soda whereby the oil in the electrode is converted into soap. Instead of caustic soda, an alkali salt may be used as electrolyte, the electrode being made the cathode in this case.
