This invention concerns a saturated hydrocarbon ammoxidation process i.e., the conversion of alkanes into a mixture containing .alpha.,.beta.-unsaturated nitriles. This invention relates more specifically to a vapour phase alkane ammoxidation process in the presence of a solid catalyst whose active phase includes molybdenum and oxygen characterized by the fact that the said phase also includes at least one element chosen from the group constituted by the alkine-earth metals, Mn, Fe, U, La and Co. The present invention is especially well-suited to the ammoxidation of propane into a mixture including acrylonitrile and propylene.
La présente invention concerne un procédé d'ammoxydation d'hydrocarbures saturés c'est-à-dire la conversion d'alcanes en un mélange renfermant des nitriles .alpha.,.beta.-insaturés. La présente invention a plus particulièrement pour objet un procédé d'ammoxydation d'alcanes en phase vapeur en présence d'un catalyseur solide dont la phase active renferme du molybdène et de l'oxygène caractérisé en ce que ladite phase active renferme également au moins un élément choisi dans le groupe constitué par les métaux alcalino-terreux, Mn, Fe, U, La et Co. La présente invention convient plus particulièrement à l'ammoxydation du propane en un mélange renfermant de l'acrylonitrile et du propylène.
