Abstract
Abstract The instant application is related to a process for the oxidation of saturated hydrocarbons and substituted saturated hydrocarbons in a vapor phase reaction over an antimonycontaining oxidation catalyst in which the hydrocarbon in the presence of a minor quantity of an inorganic or organic halide, hydrogen chloride, hydrogen bromide or hydrogen iodide or of a halogen other than fluorine, is reacted with (a) oxygen, to form unsaturated aldehydes and acids or (b) oxygen and ammonia, to form unsaturated nitriles.
