A Novel Ruthenium-Phosphorus Amorphous Alloy Catalyst for Maltose Hydrogenation to Maltitol

摘要

A ruthenium-phosphorus(Ru-P)amorphous alloy catalyst was prepared by chemical reduction of ruthenium(III)ions[Ru~(3+)]with hypophos-phite[H2PO_2~-]in aqueous solution and was applied to the liquid-phase hydrogenation of maltose.In comparison with other reference catalysts,Ru-P showed significant activity as evident in the order;Ru-P>Ru-BNi-P>Co-PRaney Ni.Further-more,this catalyst was also found to be more durable during this hydrogenation process.Special emphasis was laid on a comparative study of Ru-P and Ru-B catalysts to get an insight into the excellent catalytic performances of Ru-P.
