  • Patent number: 8110708
    Abstract: Ruthenium/activated charcoal (Ru/AC) treated with synthesized nano-ZnO (n-ZnO) is used for the first time as a novel composite catalyst in one-step self-condensation of acetone (DMK) to methyl isobutyl ketone in the gas phase. The DMK self-condensation was performed under atmospheric pressure, in a tubular glass fixed-bed microreactor, under DMK and H2 continuous flow at temperature in the range of 523 to 648 K. Addition of n-ZnO to Ru/AC resulted in a pronounced increase in the degree of dispersion of Ru and in the acidic/basic sites concentration ratio. For the one-step synthesis of MIBK at 623 K, the composite catalyst with 2.5 wt % Ru loading was an active and selective bi-functional composite catalyst with balanced acid/base and hydrogenation properties. At 523 K, isopropyl alcohol, product of DMK-direct hydrogenation, was produced in high selectivity for instantly investigated composite catalyst.

  • Patent number: 7951976
    Abstract: Several metal-supported catalyst compositions based on nano-crystalline zinc oxide were synthesized and characterized by X-ray powder diffraction (XRD), Carbon dioxide temperature programmed desorption (CO2 TPD), and nitrogen adsorption at ?196° C. The Pd-supported nano-ZnO mixed with different oxides such as Cr2O3, CrO3, MgO, and ?-Al2O3 showed high catalytic activity in acetone condensation in gas-phase process under hydrogen flow. This reaction involves the base-acid coupling of acetone to form mesityl oxide, followed by its hydrogenation to methyl isobutyl ketone (MIBK). The novel catalyst 1% wt. n-Pd/n-ZnCr2O4 was utilized during gas-phase reaction during production of MIBK. MIBK selectivity was 70-72% at 66-77% acetone conversion at 300-350° C. Diisobutyl ketone (DIBK) was the main by-product, with a total MIBK+DIBK selectivity up to 88%. The prepared catalysts showed stable activity and may be used repeatedly and for a longer period of time.

  • Publication number: 20040181057
    Abstract: The present invention discloses an aminothiol compound having a general formula I wherein R1-R5 are substitutable ligands. Such compound can perform as a superior catalyst in an asymmetric addition reaction of organic metal compounds and aldehyde. According to the present invention, the aminothiol compound is needed only less than 0.02% based on main reactants to obtain enantioselectivity higher than 98% enantiomeric excess, whereby the asymmetric reactions can become very economic.

  • Patent number: 6765119
    Abstract: The invention relates to a process for the preparation of saturated C3-C20-alcohols in which a liquid hydrogenation feed comprising at least one C3-C20-aldehyde is passed over a bed of a hydrogenation catalyst in the presence of a hydrogen-containing gas, which comprises adding to the hydrogenation feed an amount, homogeneously soluble therein, of a salt-like base. The addition of base suppresses side reactions, such as acetalization, aldolization, Tischtschenko reaction or ether formation.

  • Patent number: 6486355
    Abstract: Disclosed is a composition, a method of making and a method of using critical clusters for asymmetric synthesis using substantially optically-pure chiral solvent molecules in a supercritical fluid. The solvent molecules are capable of forming a multipoint hydrogen bonded solvate as they encage at least one solute molecule. The encaged solute molecule is capable of reacting to form an optically active chiral center. In another aspect, there is disclosed a method of directing the position of bonding between a solute molecule and a ligand involving encaging the solute molecule and the ligand with polar solvent molecules in a supercritical fluid under conditions of temperature and pressure sufficient to change electric charge distribution in the solute molecule.
