Abstract: The invention relates to multi-metal oxides of general formula (I) Mo12-a-b-c Va M b M c Ox, wherein the variables have the following meaning: M = W and/or Nb, M = Ti, Zr, Hf, Ta, Cr, Mn, Re, Ag, Cu, Si, and/or Ge, a = 0.1-6, b = 0-6, c = 0-6, with the proviso that a + b + c = 0.1-6 and x = a number determined by the valence and abundance of elements in (I) different from oxygen. Said oxides are used as combustion moderators for gas-producing mixtures. They can be used, particularly in air bag systems, as a mixture or two-phased multi-metal oxide mass with multi-metal oxides containing copper.

Abstract: The invention relates to a method for producing enol ethers of formula (I), in which R is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical, which radicals can carry other substitutes that do not react with acetylenes or allenes; the R radicals are, independently of each other, hydrogen, or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radicals, which can interconnect forming a ring; and m stands for 0 or 1. In this method, acetals or ketals of formula (II) are reacted with acetylenes or allenes of formula (III) or (IV), in which the R and R radicals have the aforementioned meanings. The reaction takes place in the gas phase, at high temperature, in the presence of a heterogeneous catalyst containing zinc or cadmium together with silicon and oxygen.

Abstract: A process for the selective oxidation of non-cyclic unsaturated hydrocarbons (UHC) other than isobutene, especially non-cyclic poly-unsaturated alkenes, to give oxygen-containing organic compounds. The process comprises reacting the UHC, or a gas mixture containing UHC, at 150-600 (preferably 180-450) deg C with an optionally supported catalyst material based on a silver- vanadium mixed oxide of formula AgxMyVOz (I), in which x = 0.001-3; M = another element, preferably from main groups 1-6 or sub-Groups 1-3 and 5-8; y = 0-0.5; z = the number required for charge neutrality between cations and oxygen anions. Preferably x = 0.001-1, with y and z as above. Preferred (I) is a beta - or delta -silver-vanadium bronze. The catalyst may be used as an unsupported bulk material, or supported on clay, pillared clay, zeolites, aluminium phosphate, silicon carbide, silicon nitride, boron nitride, carbon, or oxides of titanium, zirconium, zinc, thorium, magnesium, calcium, barium or silicon. The process comprises (a) at least partial reduction of (I) by contact with the UHC or an oxygen-free gas mixture containing UHC, and (b) re-oxidation of the reduced catalyst with gas containing molecular oxygen or another oxygen- containing oxidising agent. Stage (a) is preferably carried out with a gas containing the UHC and a sub-stoichiometric amount of O2 (especially using air) or other oxidising agent as above, preferably dinitrogen oxide.
