Tandem catalysis for the hydrogenation rearrangement of furfural (FA) provides an attractive solution manufacturing cyclopentanone (CPO) from renewable biomass resources. The CuNi/Al-MCM-41 catalyst was synthesized and afforded excellent catalytic performance with 99.0% conversion 97.7% selectivity to CPO in a near-neutral under 2.0 MPa H2 at 160 °C 5 h, much higher than those on other molecula...

The dielectric behaviors of some small symmetric ketone molecules, including acetone, 3-pentanone, cyclopentanone, 4-heptanone, and cyclohexanone, were investigated as a function of temperature (T) over a wide frequency range from 50 MHz (3.14 × 10(8) s(-1), in angular frequency) to 3 THz (1.88 × 10(13) s(-1)). The temperature dependencies of the rotational diffusion times (τ(r)) determined usi...

The conversion of biomass resources into high-value fuels and chemicals using thermochemical methods has become an attractive method energy utilization. In this study, natural minerals were used as raw materials; the acidic sites introduced by ball-milling modification, aldol condensation reaction biomass-based cyclopentanone molecule was carried out under solvent-free conditions. It found that...
