FIELD: chemistry.

SUBSTANCE: present invention relates to an improved method of producing at least one product of partial oxidation and/or ammoxidation of a hydrocarbon, chosen from a group containing acrolein, acrylic acid, methacrolen, methacrylic acid, acrylonitrile and methacrylonitrile. At least one saturated hydrocarbon is subjected to heterogeneous catalysed dehydrogenation in a gas phase, obtaining a gas mixture, containing at least one partially dehydrogenated hydrocarbon. Components of the gas mixture except saturated hydrocarbon and partially dehydrogenated hydrocarbon are left in the mixture. Alternatively, the extra gas mixture obtained is partially or completely separated, and the gas mixture and/or extra gas mixture are used for obtaining another gas mixture, containing molecular oxygen and/or molecular oxygen and ammonia. This gas mixture is subjected to at least single heterogeneous catalysed partial oxidation and/or ammoxidation of at least one partially dehydrogenated hydrocarbon contained in the gas mixture and/or extra gas mixture. The gas mixture, extra gas mixture and/or the other gas mixture, before at least one partial heterogeneous catalysed oxidation and/or ammoxidation, are subjected to at least a single mechanical separation, aimed at separating particles of solid substance contained in the above mentioned gas mixtures.

EFFECT: reliable and continuous realisation of the process for relatively long periods of time.
