The liquid-phase hydrogenation of TMCB for preparation of CBDO by fluorine-modified Ruthenium-Stannum bimetallic catalysts
A series of Ruthenium-Stannum bimetallic catalysts were prepared using the isovolumetric impregnation method and investigated for the liquid-phase hydrogenation of 2,2,4,4-tetramethyl-1,3-cyclobutanedione to its corresponding 2,2,4,4-tetramethyl-1,3-cyclobutanediol. The effects of the reaction temperature and pressure, fluorine-modified alumina, reaction solvent, and catalyst particle size on the catalytic performance were discussed. The optimum reaction conditions were obtained with a temperature of 80 ℃, a hydrogen pressure of 4.0 MPa, and a reaction solvent of tetrahydrofuran. In addition, characterization techniques, such as BET, XRD, TEM, NH3-TPD, and Py-IR, showed that the active component nanoparticles were effectively introduced into the alumina carriers, and the alumina was modified by a low concentration of NH4F solution (0.05 mol/L), which ensured that the complete conversion of 2,2,4,4-tetramethyl-1,3-cyclobutanedione was obtained while maintaining a selectivity of over 95 % for the 2,2,4,4-tetramethyl-1,3-cyclobutanediol.
