  • Process and catalyst for olefin hydration
    Patent number: 4329520
    Abstract: Olefins can be hydrated to the corresponding alcohols with a hydration catalyst comprising a calcined support consisting of diatomaceous earth, bentonite, silica, cornmeal and cellulose which has been calcined and then impregnated with phosphoric acid.
    Type: Grant
    Filed: February 27, 1981
    Date of Patent: May 11, 1982
    Assignee: Union Carbide Corporation
    Inventors: Percy R. Kavasmaneck, David B. Stanton, Paul D. Sherman, Jr.

  • Hydroformylation of ethylene with higher olefins
    Patent number: 4262142
    Abstract: In a rhodium-catalyzed hydroformylation process employing olefin reactants having from 3 to 20 carbon atoms to produce products rich in normal aldehydes, the efficiency of the catalyst in producing such products is substantially uneffected and propionaldehyde is also produced by employing ethylene as a coreactant along with the olefin.
    Type: Grant
    Filed: December 28, 1979
    Date of Patent: April 14, 1981
    Assignee: Union Carbide Corporation
    Inventors: Paul D. Sherman, Jr., Stephen C. Winans, Dennis G. Morrell
  • Hydroformylation process
    Patent number: 4260828
    Abstract: In a rhodium-catalyzed hydroformylation process which produces aldehydes from alpha-olefins, the stability of a rhodium catalyst complexed with carbon monoxide and a triarylphosphine ligand is improved by providing an alkyldiarylphosphine ligand in the catalyst-containing reaction medium.
