Abstract: The preparation of epoxide from olefins, hydrogen and oxygen is carried out using an oxidation catalyst based on titanium or vanadium silicalite with zeolite structure, which contains 0.1-20 wt.% of platinum metals(s) selected from ruthenium, rhodium, palladium, osmium, iridium and platinum, each of which is present in more than one different bond energy state. An inert carrier gas selected from nitrogen, noble gases, carbon dioxide and 1-8 carbon C hydrocarbons may be used. The molar ratio of H2:O2 is 1:(1-10) and of inert gas to olefin > 20:1. The molar ratio of O2 to olefin or olefin and inert gas, if used, is

Abstract: Described is a method of producing reactive halogen-free polyisobutene having more than 50 mole % of terminal double bonds and a mean molecular weight Mn of 500 to 5000 Daltons by the cationic polymerization of isobutene or isobutene-containing hydrocarbon mixtures in the liquid phase, the polymerization being carried out at a temperature of -30 to +40 DEG C over a heterogeneous polymerization catalyst which includes at least one element which acts as promoter selected from the Ist, IInd, IIIrd, IVth, Vth, VIIth or VIIIth sub-group of the periodic table of the elements or from the IInd, IIIrd, IVth, Vth or VIth main group of the periodic table, or several such elements, each in the form of an oxygen-containing compound, plus zirconium in the form of an oxygen-containing compound, the catalyst not containing technically significant amounts of halogens.
