Aqueous phase hydrogenation of levulinic acid to 1,4-pentanediol.
For the first time, Mo modified Rh/SiO2 was found to be an effective catalyst for the aqueous phase selective hydrogenation of levulinic acid to 1,4-pentanediol. Over such a catalyst, high levulinic acid conversion (100%) and 1,4-pentanediol yield (70%) can be achieved at low temperature (353 K).
