Abstract
Co and Pd supported on Nb 2O 5 catalyst was active for the hydrogenation of maleic anhydride to γ-butyrolactone and tetrahydrofuran in the liquid-phase. The catalyst was more active than Co and Pd supported on diatomaceous earth, SiO 2 and Al 2O 3. Co and Pd seem to be stable on Nb 2O 5. Nb 2O 5 · nH 2O was active for the hydration of succinonitrile to β-cyanopropionamide, that is an intermediate for α-pyrrolidone, in the liquid-phase. Niobium oxide showed unique catalytic activities, especially, in the presence of water.
