PROCESS FOR THE METATHESIS OF COMPOUNDS COMPRISING A DOUBLE OLEFIN BOND, IN PARTICULAR OLEFINS

摘要

The present invention relates to a process for the metathesis of one or more reagents comprising a linear or branched hydrocarbon chain comprising an olefinic double bond Csp2 = Csp2, in which this or these reactants are reacted with a supported metal compound comprising a support based on aluminum oxide on which is grafted a tungsten hydride. Typically, the reagent or reagents each comprise from 2 to 30 carbon atoms. The reagent may be in particular an olefin. For example the process produces propylene from ethylene and butene. / P
