Isomerizable olefinic hydrocarbon feeds containing greater than 3 carbon atoms and less than 50 are subjected to double bond shift by catalytic reaction at 0 DEG to 300 DEG C. for 0.001 to 50 hours. The catalyst is formed by the interaction of one mole of iron salt and 0.5 to 6 moles of a reducing organometallic compound. Exemplified products are given from treatment of 1,5-cyclooctadiene, 1-hexene, 4-vinylcyclohexene, 1-hexadecene and C15-20 a -olefine fraction from cracked petroleum wax.ALSO:A catalyst is formed by the interaction of a mol of iron salt and 0.5 to 6 mols of an iron-salt-reducing organometallic compound. The solid catalyst may be formed in an inert media or in the presence of an olefinic hydrocarbon to be isomerised. The catalyst may be deposited on an inert support. Numerous examples are given of the substances used in the process. |
