Abstract: An isobutenylcyclohexene (IBCH) is produced by reacting under disproportionation conditions an isoolefin with a vinylcyclohexene (VCH), or by reacting an isoolefin and a compound derivable from a VCH by homodisproportionation involving the elimination of ethylene, in the presence of a supported rhenium heptoxide disproportionation catalyst promoted with at least one transition metal in the form of the elemental metal and/or an oxide thereof, for example either copper or zinc.

Abstract: 2,3-dimethylbutene-1 (2,3-DMB1) is produced from propene by a process comprising the steps of:(A) converting propene in one or more stages to a product comprising 2,3-dimethylbutene-2 (2,3-DMB-2) under conditions whereby the proportion of 2,3-DMB-2 in the product is maximised,(B) separating 2,3-DMB-2 from the product of step (A), and(C) contacting the 2,3-DMB-2 separated in step (B) with a catalyst active for the isomerisation of 2,3-DMB-2 to 2,3-DMB-1 under conditions whereby 2,3-DMB-2 is isomerised to 2,3-DMB-1.

Abstract: A process for the production of isobutylbenzenes in particular, isobutylbenzene itself, is provided. The process is in two stages and comprises (1) reacting a vinylcyclohexane with an isoolefin of formula (R)(R.sup.1)C.dbd.C(CH.sub.3).sub.2 in the presence of a dismutation catalyst to produce an isobutenylcyclohexene and (2) contacting the isobutenylcyclohexene with a dehydroisomerisation catalyst to produce an isobutylbenzene. Examples of vinylcyclohexenes which can be used include 4-vinylcyclohexene and styrene.

Abstract: An isobutylbenzene (IBB) is produced from an isobutenylcyclohexane (IBCH) by contacting at elevated temperature the IBCH in the presence of a molecular oxygen-containing gas with a catalyst comprising a supported transition metal in the form of the elemental metal and/or a compound thereof, for example palladium supported on alumina.
