Abstract

Heteropoly compounds of empirical composition Mo10Te1-10Mn2-20P2-20O39-120 in whic P is combined with 3 or 4 atoms of oxygen, are claimed per se and their preparation described, e.g. by dissolving separately the requisite amount of molybdenum salt, a tellurium salt and a manganese salt in water, adding phosphoric acid to the manganese salt solution, adding the tellurium salt solution to the molybdenum salt solution, adding the manganese salt phosphoric acid mixture to the Mo-Te salt mixture, drying and baking at 400 DEG C. for 16 hours. To provide a ratio of from 5Mn to 6P to 3Mn to 2P an alternative procedure is described in which ammonium molybdate is dissolved in water, TeO2 is dissolved in HCl, MnCl2 is dissolved in water and H3PO4 added, combining the solutions and baking at 400 DEG C.ALSO:Catalysts of general formula Mo10Te1- 10Mn2- 20 P2- 20O39- 120 in which P is combined with 3 or 40 are used to oxidize in vapour phase propylene or isobutylene to acrolein and acrylic acid or methacrolein and methacrylic acid respectively at 325-550 DEG C. The same olefins yield in the presence of the same catalyst and a similar gaseous mixture containing additionally ammonia, acrylonitrile or methacrylonitrile at 375-500 DEG C. The oxidation/ammoxidation may be effected in a fixed or fluidized bed using either steam or an inert gas as diluent. Numerous examples are given in which variables such as catalyst composition, reaction temperature, pressure and ratio of reactants are changed. Acetonitrile is mentioned as a by-product (see Example XIV).ALSO:Oxidation/aminoxidation catalysts comprise heteropolycompounds of formula Mo10, Te1-10 Mn2-20P2-20O39-120 in which P is combined with 3 or 40 and their preparation from mixed acid-salt solutions is described. The catalyst may be supported and used in fluidized on fixed beds. Specified carriers are SiO2, diatomaceous earth, Kieselguhr, silicon carbide, clay, Al2O3 or C. Particles of particular mesh size and supports of particular preface area are described.
