Hydroformylation of olefins

Patent Pending Side reactions of the olefins are the isomerization and hydrogenation of the olefinic double bond. While the alkanes resulting from hydrogenation of the double bond do not participate further in the reaction, the isomerization of the double bond with subsequent formation of the n-alkyl complexes is a desired reaction. The hydrogenation is usually of minor importance; However, Cobalt-phosphine-modified catalysts can have an increased hydrogenation activity, where up to 15% of the olefin is hydrogenated.
