Hydrogenation of Crotonaldehyde and Acetaldole with Modified Pd Carrier Catalysts. I. On the Influence of a Titanium Modification to Pd/Al2O3 CatalystsThe modification of Pd/Al2O3 catalysts with titanium was studied in the hydrogenation of crotonaldehyde and acetaldole. In the result of the titanium modification the hydrogenation activity is increased and the formation of carbon monoxide is decreased. An electronic and geometric ensemble effect should be the reason for the palladium titanium interaction. The mechanism of the acetaldole conversion to butyraldehyde at 160°C is mainly determined by hydrogenolysis in one step and at 200°C by two steps consisting in dehydratization and hydrogenation.
