Abstract
Catalyst compositions of palladium supported on alumina or zirconium oxide supports having low or no silicon dioxide contents and having a specific surface area or modified with alkali, alkaline earth, or phosphine oxide compounds are selective in a vapor phase hydrogenolysis reaction to convert cyclic acetal compounds and/or cyclic ketal compounds in the presence of hydrogen to their corresponding hydroxy ether hydrocarbon reaction products.
