Abstract

Pure iron, which is useful as a catalyst for the synthesis of ammonia, is prepared by treating ferric nitrate solution with just sufficient silver nitrate to precipitate any chloride present, filtering, evaporating the solution to dryness, partially converting the nitrate into oxide by gentle ignition, washing out the residual nitrate together with any oxidized sulphur product, and finally reducing the ferric oxide. An inert support, such as pumice or asbestos, may be added just prior to ignition; and a promoter may be incorporated with the catalyst by adding ammonium molybdate, potassium osmate, titanium nitrate, uranium nitrate, or an alkali tungstate, to the purified ferric oxides before reduction. The product is preferably heated in pure ammonia gas. Specifications 19249/10, 5833/11, 24657/11, and 25252/11 are referred to.ALSO:Potassium osmate is prepared by oxidizing metallic potassium with water vapour and adding osmium anhydride to the resulting liquid. Specifications 19249/10, 5833/11, 24657/11 and 25252/11, [all in Class 1 (i), Chemical processes &c.], are referred to.
