Abstract

Abstract: A series of heteropolyacid supported on ammonium Y zeolite (HPA-NH4 YZ) catalysts were prepared and used for the catalytic oxidation of furfural to 2(5H)-furanone in aqueous hydrogen peroxide. The catalysts were characterized by PXRD, FTIR, TGA, and SEM analyses. The organic-solvent-free reaction was optimized on temperature, duration, loading of catalyst, and the equivalent of H2 O2 . The 20%PTA-NH4 YZ catalyst showed the best catalytic activity giving 2(5H)-furanone in 40% isolated yield by solvent extraction under optimized conditions (20 wt% cat., 100 °C, 90 min, 7.5 eq. 30%H2 O2 ). In addition, around 20% of succinic acid was recovered from the aqueous layer.
