✦ Synopsis

Hydrogenation of Crotonaldehyde, Butyraldehyde and Acetaldole with Modified Ni Carrier Catalysts. I. On the Influence of a Copper Modification of Ni/Kaolin Catalysts

The hydrogenation of crotonaldehyde, butyraldehyde and acetaldol in the presence of Ni‐Cu catalysts is a single‐centre reaction, whereas the decarbonylation of crotonaldehyde is a multi‐centre reaction. The ratio between the specific activities of the hydrogenation of the CC double bond and the carbonyl group is two. In the conversion of acetaldol the hydrogenolysis to butyraldehyde can be neglected in comparison with the hydrogenation to butan‐1,3‐diol.
