Influence of residual chloride ions in alumina-supported cobalt catalysts on catalytic activity in ketone and aldehyde hydrogenation

摘要

The influence of residual chloride ions on the catalytic activity of Co/Al2O3 was investigated for liquid-phase hydrogenation of ketones and aldehydes using Cl--free and Cl--containing catalysts. The Cl--free catalyst showed high activity for hydrogenation of both, whereas the Cl--containing catalysts showed very low activity for ketone hydrogenation.
