  • Catalysts for cycloalkanes oxidation and decomposition of cycloalkyl hydroperoxide
    Patent number: 7081552
    Abstract: A cyclic ketone/alcohol mixture is prepared by catalytic oxidation of the corresponding cycloalkane or catalytic decomposition of the corresponding cycloalkyl hydroperoxide. Gold supported on a porous crystalline silicate containing less than about 2 wt. % aluminum or a crystalline phosphate is used as a catalyst. The support material optionally contains one or more heteroatoms.
    Type: Grant
    Filed: August 17, 2004
    Date of Patent: July 25, 2006
    Assignee: Solutia Inc.
    Inventors: Larisa V. Pirutko, Alexander S. Kharitonov, Mikhail I. Khramov, Anthony K. Uriarte
  • Cyclohexane oxidation catalysts
    Publication number: 20040158103
    Abstract: A cycloalkane, such as cyclohexane, is catalytically oxidized to form a ketone/alcohol mixture. A cycloalkane-containing reaction mixture is contacted with a source of oxygen in the presence of a catalytic effective amount of gold supported on a crystalline zeolite-like support. The zeolite-like support optionally contains one or more heteroatoms.
