摘要： The invention relates to the skeleton isomerization of alkenes and, more particularly, to the catalyst for the isomerization reaction, the catalyst being prepared by treating an oxide of a metal of the group comprising aluminium, titanium, magnesium, silicon, chrome, zirconium, iron and their mixtures, preferably an active alumina, with a silicon compound, preferably an alkyl ester of the orthosilicic acid, and then subjecting the thus treated oxide to drying and to a controlled oxidation. Thus catalyst is obtained which permits higher yields and selectivity of the isomerization reaction to be achieved, as well as a longer operative life of the catalyst before the regeneration thereof.

摘要： A new catalyst is described which is useful in the ammoxidation or oxidation of olefins. It consists of a mixture of oxidation compounds of uranium, tellurium and molybdenum, which may be accompanied by an activator consisting of an oxidation compound of an element selected from groups Ib, IIa, IIb, IIIa, IIIb, IVa, Va, VIb, VIIb and VIII of the periodic system, and is represented by the formula: U.sub.a Te.sub.b Mo.sub.c Me.sub.d X wherein, U is uranium, Te is tellurium, Mo is molybdenum, Me is the activator element, X is the oxygen necessary for saturating the other valences, a is 1, b is 1 to 8, c is 0.1 to 1 and d is 0 to 5. In the use of that catalyst, unsaturated nitriles are prepared by contacting a mixture, in vapor phase, of an olefin, ammonia and oxygen or a gas containing oxygen in the presence of the catalyst; and olefins are converted to oxygen containing compounds or dienes by contacting, in vapor phase, a mixture of the olefin and oxygen in the presence of the catalyst.
