A relatively selective hydrogenation of 1,5-cyclooctadiene to cyclooctene has been achieved in cyclooctane solution at atmospheric pressure using a powder catalyst with 0.6% (by wt.) palladium on γ-alumina. The cyclooctene yields are temperature independent within 30 to 50°C, they are, however, markedly decreased with the use of the tablet catalyst.
