Abstract
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.
