摘要 |
The present invention relates to a process for the ammoxidation of saturated hydrocarbons, that is to say the conversion of alkanes to a mixture containing alpha , beta -unsaturated nitriles. The subject of the present invention is more particularly a process for the ammoxidation of alkanes in the vapour phase in the presence of a solid catalyst, the active phase of which contains molybdenum and oxygen, characterised in that the said active phase also contains at least one element chosen from the group consisting of the alkaline-earth metals, Mn, Fe, U, La, Co, Ni, Zn, Ag, Cd, W, Zr, Pb, Te, Ga, Al, B, Nb and Ta. The present invention is more particularly suitable for the ammoxidation of propane to a mixture containing acrylonitrile and propylene. |
