    摘要: A process for making ethylene glycol by feeding reactants including 1,2-dioxygenated organic compounds, an organometallic homogeneous catalyst, and hydrogen to a hydrogenation reactor, reacting at least a portion of the reactants with hydrogen in the presence of the organometallic homogeneous catalyst to produce a reaction product mixture containing ethylene glycol, and passivating the catalyst by contacting the catalyst with a carbon monoxide to thereby suppress the formation of by-product diols other thatn the ethylene glycol primary product, and suppress the formation of by-product tetrols and by-product glycolaldehyde acetals; and separating at least a portion of the ethylene glycol from the reaction product mixture.

    摘要: Use of a unique supramolecular assembly of a pyridylphosphine ligand and a metal centered porphyrin complex is shown to give unprecedented selectivities to branched aldehydes via rhodium catalyzed hydroformylation of unsubstituted linear alpha-olefins such as propylene and 1-octene. Increasing the syngas pressure is shown to have a beneficial effect on branched aldehyde selectivity as is increasing the ratio of carbon monoxide to hydrogen used in the hydroformylation reaction.
