Summary: | Levulinic acid (LA) is one of the most significant cellulose-derived compounds. γ-Valerolactone (GVL) and 1,4-pentanediol (1,4-PDO) are considered to be important chemical intermediates. Direct conversion of LA to GVL and GVL to 1,4-PDO was achieved
via
chemoselective hydrogenation by supported copper catalysts. We studied the transformation of LA to GVL in water and alcohol, and the pathway of the reaction was also studied. LA was converted to GVL catalyzed by the Cu (30%)-WO

Direct conversion of cellulose-derived levulinic acid into γ-valerolactone and γ-valerolactone into 1,4-pentanediol was carried out by chemoselective hydrogenation catalyzed through supported copper-catalysts. |
