In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Efficient formation of γ-valerolactone in the vapor-phase hydrogenation of levulinic acid over Cu-Co/alumina catalyst, published in 2020-05-31, which mentions a compound: 591-12-8, Name is 5-Methylfuran-2(3H)-one, Molecular C5H6O2, Synthetic Route of C5H6O2.
Vapor-phase hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL) was investigated over Al2O3-supported bimetallic Cu-Co catalysts with different Cu/Co weight ratios under ambient H2 pressure. The bimetallic Cu-Co/Al2O3 catalyst with a Cu/Co weight ratio of 8/12 exhibits an excellent catalytic activity and stability: it showed a high GVL productivity of 5.46 kg kg-1cat. h-1 with a GVL selectivity higher than 99% at 250°C for 24 h. In the characterization of the catalysts, powder X-ray diffraction suggests that bimetallic Cu-Co particles on the Cu-Co/Al2O3 catalysts are composed of an alloy.
