Hydrogenation of dienes

摘要

Process for the selective hydrogenation of diolefinic compounds to monoolefinic compounds employing catalyst consisting essentially of elemental nickel on an inorganic support in the presence of hydrogen and at least one nitrogen-containing compound is disclosed. Selective hydrogenation of the less substituted of the two carbon-carbon double bonds of the diolefinic compound is achieved while isomerization of the more highly substituted, non-hydrogenated double bond, is minimized.
