Abstract
301,778. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 5, 1927. Metal carbonyls.-In forming metal carbonyls by reaction of carbon monoxide upon metals obtained by reduction, substances containing metals or lower metal oxides are treated to render them reactive towards carbon monoxide by submitting them first to oxidation, for example, by heating with oxygen, air, water, carbon dioxide &c. and then to reduction which may be carried out under pressure. The oxidation and reduction may be repeated. In examples, the treatment is described of scrap iron in the form of turnings, hammer scale consisting mainly of ferrosoferric oxide, and the residual nickel which remains after repeated alternate treatment with carbon monoxide and hydrogen, and which can no longer be activated by treatment with hydrogen.
