Catalytic oxidation of mono‐ethenoid fatty acids; The catalytic influence of cations of metals of the typical and transitional series in autoxidation processes

Abstract

AbstractThe influence of metal cations of the typical and transitional series in catalytic oxidation of oleic acid has been investigated over a wide range of conditions. The results of a series of oxidations, in which the catalyst metal ion content was adjusted to a constant value, have afforded new information concerning the intrinsic effect of metal ions on oxygen absorption by mono‐ethenoid acids.A new relative order of efficiency of metal cation catalysts in autoxidation processes has been obtained. The catalytic activity of the metal ions is correlated with their atomic structure and is shown to be a periodic function. A theory of catalytic activity is advanced applicable to metals used for promoting gaseous oxidation of unsaturated fatty acids and esters, and for the oxidation of parent oils.
