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.
