Cyclohexanone by catalytic hydrogenation - of phenol

Cyclohexanone by catalytic hydrogenation - of phenol

The gas phase reaction at pref. 120-180 degrees C utilises a catalyst contg 0.1-5% Pt metal on active alumina support and 5-50% alkaline earth hydroxide and/or oxide. Specif. area is >110 m2/g and >40% of pores are 100-500 A. The catalyst is simple to prepare, has a long life, low Pt content a...

Zusammenfassung:The gas phase reaction at pref. 120-180 degrees C utilises a catalyst contg 0.1-5% Pt metal on active alumina support and 5-50% alkaline earth hydroxide and/or oxide. Specif. area is >110 m2/g and >40% of pores are 100-500 A. The catalyst is simple to prepare, has a long life, low Pt content and high selectivity.
