ABSTRACT:
This present invention relates to a disproportionation catalyst and to a process for preparing a disproportionation catalyst comprising forming a calcined composite comprising at least one of molybdenum and rhenium supported on an inorganic oxide support and contacting the calcined composite with an organoborane compound. The invention further relates to a process for the disproportionation of olefinic hydrocarbons comprising contacting at least one olefinic hydrocarbon with a catalyst comprising at least one of molybdenum and rhenium supported on an inorganic oxide support promoted with an organoborane compound. More specifically, the invention relates to the uses of an organoborane compound promoted molybdenum and rhenium supported on an inorganic oxide support for the production of linear alpha olefins from a mixture of internal olefins and ethylene. The invention also relates to the application of the described promoted catalyst for the production of 1,6-heptadiene and 1,6-octadiene from the reaction of cyclopentene with ethylene and propylene, respectively, and the fact that the presence of organoborane in the catalyst allows the reaction to be carried out at very mild temperature while obtaining high product selectivity.
