This invention pertains to an improved process for the hydrogenation of acetylenic compounds prepared by the condensation of ketones or aldehydes with acetylene wherein the acetylenic compounds are contacted with hydrogen in the presence of a hydrogenation catalyst under conditions for effecting hydrogenation. The improvement in the process resides in utilizing a novel cocatalyst system for hydrogenating the acetylenic compounds to paraffins. The cocatalyst converts the inhibiting impurity in the feed to a noninhibiting species and comprises palladium and platinum, typically in a ratio of from 1 to 40 weight parts palladium per weight part platinum. |
