Provided in the present invention is an iridium-based catalyst, which is characterized in that the chemical structural formula of the iridium-based catalyst is:

##STR00001## wherein Ph is a phenyl, R is a methyl or an ethyl, and X is one or more of CH.sub.3CO.sub.2, NO.sub.3, Cl, BF.sub.4, PF.sub.6 and SbF.sub.6. In the present invention, a rhodium-based catalyst in the prior art is replaced with the iridium-based catalyst, such that the reaction cost is reduced, and the yield of reactants is increased.

The invention relates to a method of producing carbonyl compounds, more particularly C.sub.2-C.sub.4 ketones and aldehydes. The method is based on the gas-phase oxidation by nitrous oxide of C.sub.2-C.sub.4 alkane-olefin mixtures, such as a butane-butylene fraction or a propane-propylene fraction, obtained by thermal and/or catalytic cracking, to produce C.sub.2-C.sub.4 ketones and aldehydes. The process is carried out under continuous flow conditions at a temperature of 300-550 C. and pressure of 1-100 atm, without prior isolation of individual olefins from the fractionation products and in the absence of a catalyst. The process provides for high productivity, high overall selectivity for ketones and aldehydes, and explosion-safe operation.
