ABSTRACT:
Zerovalent Group VIII metals dispersed on alpha-alumina are hydrothermally stable hydrogenation catalysts which may be used advantageously in the reduction of aqueous solutions of carbohydrates. The use of ruthenium on alpha-alumina in the hydrogenation of glucose affords sorbitol in excellent yields with quite high selectivity, and with minimal leaching of either ruthenium or alumina.
