ALKANE METATHESIS CATALYST, METHODS OF USE AND THE PREPARATION THEREOF

摘要

The invention concerns an alkane metathesis catalyst, its production and use. The catalyst comprises a Group V, VI or VII metal alkyl with the metal in its highest oxidation state, preferably Ta or W, and the alkyl of C1-C4, preferably together with alkylidene and/or alkylidyne ligands, in particular -Me, =CH2 and ≡CH, on a metal oxide support, preferably silica partially dehydroxylated at 200 or 700 °C. Substrates include cycloalkanes, preferably cyclooctane.
