Partial hydrogenation of the aromatic rings in lignin was confirmed by H-1 NMR spectroscopy. The ability of the catalyst to hydrogenate the lignin model compound 2-methoxy-4-propylphenol is critically dependent on the reaction medium: hydrogenation proceeds faster in aqueous ethanol than in aqueous dioxane, aqueous methyl cellosolve or anhydrous ethanol while no hydrogenation occurs in aqueous DMF.},
