Filed: 1927-02-16
Abstract: 295,137. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 16, 1927. Hydrogen peroxide and compounds containing active oxygen, obtaining. - Metallic apparatus employed in the preparation or treatment of hydrogen peroxide or solutions of other substances giving off oxygen, such as persulphuric acid, persulphates, perborates, sodium peroxide, &c. are made of silver or base metals or alloys thereof free from mercury, in a carefully smoothed and highly polished condition. In the electrolytic production of hydrogen peroxide with cathodes of such materials, sufficient conductivity is imparted to the electrolyte by salts or acids which do not attack these materials. Phosphoric acid may be used with cathodes of silver. If sulphuric acid solutions are to be treated high-grade silicon steel is a suitable metal; with nitric acid solutions chromium and other high-grade steels may be used Nickel-chromium steel is an advantageous material. Alloys of silver with metals which readily give mixed crystals are especially suitable. The metal may be deposited on a foundation material by chemical, electrolytic, or mechanical means ,or may be diffused into the surface of the foundation metal by heat treatment. At the points where metallic parts are in contact with both liquid and gaseous phases they may be protected by lacquer or hard rubber to prevent roughening. Electrolytic preparation of hydrogen peroxide may be carried out in a diaphragm cell having as cathode a clean polished spiral of silver wire; the electrolyte is a phosphoric acid solution of 0.7 per cent strength, the current density at the cathode is 0.06 amperes per sq. cm., and oxygen is supplied at a pressure of 100 atmospheres. In another example the cathode is a plate of chromium-nickel steel, the electrolyte is a 1 per cent solution of nitric acid, and the cathode current density is 0.1 amperes per sq. cm.
