The invention relates to a method of producing carbonyl compounds , more particularly C2 - C4 ketones and aldehydes . The method is based on the gas - phase oxidation by nitrous oxide of C2 - C4 alkane - olefin mixtures , such as a butane butylene fraction or a propane - propylene fraction , obtained
by thermal and / or catalytic cracking , to produce C2 - C4 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 .
