  • Fluorine-containing catalytic system for expoxidation of alkenes
    Patent number: 4994588
    Abstract: A process is provided for epoxidation of an alkene in the presence of an oxygen-containing gas which comprises contacting the alkene and the oxygen-containing gas under epoxidation conditions in the presence of at least one gaseous efficiency-enhancing member of a redox-half reaction pair, a performance-enhancing amount of a fluorine-containing substance and a supported silver catalyst comprising a catalytically-effective amount of silver on a solid porous support and at least one efficiency-enhancing salt of a member of a redox-half reaction pair.
    Type: Grant
    Filed: August 31, 1989
    Date of Patent: February 19, 1991
    Assignee: Union Carbide Chemicals and Plastics Company Inc.
    Inventors: Louis A. Kapicak, Alfred W. Naumann, Thomas M. Notermann, Erlind M. Thorsteinson

  • Catalytic system for epoxidation of alkenes employing low sodium catalyst supports
    Patent number: 4994587
    Abstract: A process is provided for the epoxidation of an alkene in the presence of an oxygen-containing gas which comprises contacting the alkene and the oxygen-containing gas under epoxidation conditions in the presence of at least one efficiency-enhancing gaseous member of a redox-half reaction pair and a solid catalyst, the catalyst comprising a catalytically-effective amount of silver on a solid support and an efficiency-enhancing amount of at least one efficiency-enhancing salt of a member of a redox-half reaction pair, the support having less than about 50 ppm, by weight, of leachable sodium.
