Abstract:
1. A functional group-selective hydrogenation method, comprising subjecting an organic compound having at least one first functional group to a wet hydrogenation treatment in the presence of a selective hydrogenation catalyst, thereby hydrogenating the first functional group in a substantially selective manner; wherein the at least one first functional group is selected from the group consisting of an aliphatic carbon-carbon double bond, an aromatic formyl group, and combinations thereof; wherein the selective hydrogenation catalyst comprises a carrier, palladium, and an organic sulfur compound; and wherein the palladium and the organic sulfur compound are jointly supported on the carrier; wherein the organic compound further comprises at least one second functional group selected from the group consisting of an aromatic ring-bonded halogen atom, an O-benzyl group, an aromatic ketonic carbonyl group, an N-benzyloxycarbonyl group, an aromatic nitrile group, and combinations thereof; and wherein the second functional group undergoes no substantial hydrogenation.
