Improvement of the Selectivity to Crotyl Alcohol in the Gas-Phase Hydrogenation of Crotonaldehyde Over Platinum/Activated Carbon Catalysts.

Abstract Pt/activated carbon catalysts were prepared by using [Pt(NH3)4]Cl2 as the metal precursor, and characterized by a number of techniques. The selectivity of these catalysts towards crotyl alcohol in the gas-phase hydrogenation of crotonaldehyde was considerably increased when the activated carbon support was slightly oxidized before the metal incorporation.
