Abstract: Three kinds of polymer resin supported Pd catalysts were prepared by mixing PdCl2 with alkaline styrene anion exchange resins[D392 -NH2, D382, -NHCH3, D301R, -NH(CH3)2], strongly alkaline styrene anion exchanged resin[201×7DVB, -NH+(CH3)3] and alkaline epoxy exchange resin (701, -NH2), and hydrogenating in liquid phase at 1.013×105Pa. The hydrogenation of furfural was studied under the reaction conditions such as solvent, temperature, Pd content in the supported catalyst and the amount of the catalyst. The yield of hydrogenation reaction of furfural markedly increased to 100% and the selectivity to tetrahydrofurfuryl alcohol increased to over 98% by polymer(alkaline styrene anion exchange resins D392, -NH2, D382, -NHCH3) supported palladium catalysts comparing with the yield over 70% and selectivity over 97% by palladium catalyst, in 50% alcohol 50% water or pure water solution at 1013×105Pa. The relationship between hydrogenation and the structures of functional group in the supporting resin was examined by XPSmethod.
