ABSTRACT:
Supported zerovalent palladium used in the hydrogenation of aldose cyanohydrins is rapidly deactivated. A regeneration procedure based on a water wash and acid treatment effectively restores catalyst activity to its original level. Such a regeneration procedure may be used over several cycles to afford a catalyst with essentially unaltered activity.
