Synthetic Route of C5H6O2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5-Methylfuran-2(3H)-one, is researched, Molecular C5H6O2, CAS is 591-12-8, about Enhanced activity of Ru-Ir nanoparticles over SiC for hydrogenation of levulinic acid at room-temperature.

The hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL) under mild condition is a promising but challenging process. Herein, SiC supported Ru-Ir bimetallic catalyst exhibit enhanced catalytic activity for aqueous hydrogenation of LA into GVL under mild conditions. Comparing with monometallic Ir3/SiC and Ru3/SiC, the conversion of LA over bimetallic Ru0.5-Ir2.5/SiC catalyst increase from 51.2% and 45.9% to 100% at 25°C and 0.2 MPa of H2 pressure. The enhanced catalytic activity of Ru0.5-Ir2.5/SiC catalyst originates from the electronic synergistic effect among Ru, Ir and SiC. Due to the electron transfer, electron-richened Ir nanoparticles show stronger ability for H2 dissociation, and the SiC surface produces more active sites to accommodate hydrogen species that spill over from Ir and Ru. The adsorption and hydrogenation of LA mols. occur on the surface of SiC.
