  • Patent number: 9573119
    Abstract: The invention relates to a catalyst composition comprising a mixed oxide of vanadium, titanium, and phosphorus. The titanium component is derived from a water-soluble, redox-active organo-titanium compound. The catalyst composition is highly effective at facilitating the vapor-phase condensation of formaldehyde with acetic acid to generate acrylic acid, particularly using an industrially relevant aqueous liquid feed. Additionally, the catalyst composition is catalytically active towards the formation of acrylic acid from methylene diacetate and methacrylic acid from methylene dipropionate; both reactions are carried out with high space time yields.

  • Publication number: 20160251292
    Abstract: Disclosed is a process for the reductive carbonylation of a low molecular weight alcohol to produce the homologous aldehyde and/or alcohol. The process includes conducting the reaction to produce the aldehyde in the presence of a single component catalyst complex composed of cobalt, an onium cation and iodide in a ratio of 1:2:4 without additional promoters. A ruthenium co-catalyst is used in the production of the homologous alcohol. The reductive carbonylation reaction does not require an additional iodide promoter and produces a crude reductive carbonylation product substantially free of methyl iodide.

  • Publication number: 20150080628
    Abstract: Disclosed are novel catalyst solutions comprising an organic complex of nickel, an alkyl aluminum compound, a solvent, and a phosphine compound, that are useful for the preparation of butenes, pentenes and hexenes by the co-dimerization or cross-dimerization of ethylene and propylene. Also disclosed are processes for the dimerization of ethylene and propylene that utilize these catalyst solutions. The catalyst systems described herein demonstrate that, depending on the choice of phosphine compound used with the catalytically active nickel, it is indeed possible to lower the concentration of hexene olefins relative to butenes and pentenes, even in the presence of excess propylene. The selectivity to the linear or branched pentene product can also be controlled by the selection of the phosphine compound. The catalyst solutions may be used with mixtures of olefins.

  • Patent number: 8981172
    Abstract: A ternary V—Ti—P mixed oxide is shown to catalytically dehydrate 2-methyl-tetrahydrofuran in high conversion to give piperylene, in good yield. Volatile products collected from this reaction contain piperylene in concentrations as high as 80 percent by weight. Dehydration of glycerol to acrolein in high conversion and moderate selectivity is also demonstrated. The catalyst is also shown to dehydrate other alcohols and ether substrates. The catalyst is resistant to deactivation and maintains activity between runs.

  • Patent number: 8969632
    Abstract: 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 that 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.

  • Patent number: 8921608
    Abstract: Industrially relevant product selectivities and reaction rates are obtained from rhodium catalyzed hydroformylation of propylene via the use of a novel induction period in which the supramolecular ligand assembly, the rhodium precatalyst and an initial substrate are allowed to form a hydroformylation catalyst that is more selective toward branched aldehydes. Upon heating this incubated mixture and addition of propylene, iso-butyraldehyde is obtained in higher concentrations and rates that are otherwise unattainable.

  • Patent number: 8809594
    Abstract: Disclosed is a process for the production of higher aldehydes from lower alcohols using a two-stage vapor phase heterogeneous catalyst system. Ethanol feeds afford aldehydes such as butyraldehyde and crotonaldehyde while butanol feeds yield 2-ethylhexanal and 2-ethylhexenal. Higher product selectivities are obtained when the alcohol is first dehydrogenated in the upper catalyst stage followed by aldol condensation of the resulting lower aldehyde to a higher aldehyde.
