  • Selective monoepoxidation of styrene, styrene analogs, and styrene derivatives to the corresponding oxide with molecular oxygen
    Patent number: 5145968
    Abstract: Process is disclosed for the slective monoepoxidation of styrene, styrene analogs, and styrene derivatives. Such compounds are contacted with an oxygen-containing gas in the presence of a promoted, optionally supported silver catalyst under defined reaction conditions, thereby selectively producing opoxides in good yield.
    Type: Grant
    Filed: August 15, 1989
    Date of Patent: September 8, 1992
    Assignee: Eastman Kodak Company
    Inventors: John R. Monnier, Peter J. Muehlbauer
  • Selective epoxidation of diolefins and aryl olefins
    Patent number: 5138077
    Abstract: Disclosed is a process for the selective epoxidation of olefins, including diolefins, having more than 2 carbon atoms by the catalytic oxidation of such an olefin in the presence of a supported, thallium-promoted, silver catalyst.
    Type: Grant
    Filed: July 29, 1991
    Date of Patent: August 11, 1992
    Assignee: Eastman Kodak Company
    Inventors: John R. Monnier, Peter J. Muehlbauer
  • Epoxidation catalyst
    Patent number: 5081096
    Abstract: Disclosed is a novel catalyst composition comprising a catalyst support material having deposited thereon elemental silver and a promoter selected from potassium, rubidium and cesium which are obtained by treating a catalyst precursor comprising a porous catalyst support material having deposited thereon a silver compound and a promoter selected from compounds of potassium, rubidium and cesium, with a gas comprising (i) hydrogen or (ii) an inert gas containing at least about 4 volume percent hydrogen at elevated temperatures. The disclosed catalysts are particularly useful in the partial oxidation of butadiene to produce 1,2-epoxy-3-butene.

  • Selective epoxidation of olefins
    Patent number: 4950773
    Abstract: Process is disclosed for the selective epoxidation of olefins having no allylic hydrogens. Such olefins are contacted with an oxygen-containing gas in the presence of a silver catalyst and an organic halide under defined reaction conditions, thereby selectively producing epoxides in good yield.
    Type: Grant
    Filed: December 30, 1988
    Date of Patent: August 21, 1990
    Assignee: Eastman Kodak Company
    Inventors: John R. Monnier, Peter J. Muehlbauer
  • Preparation of aldehydes
    Patent number: 4942263
    Abstract: Olefins which are free of allylic hydrogens, and which contain two hydrogens bonded to a carbon atom which is bonded to another carbon by a double bond, from aldehydes when reacted with oxygen in the presence of an acidic silver catalyst, such as silver dispersed on .gamma.-alumina. For example, 1,3-butadiene is oxidized to crotonaldehyde.
    Type: Grant
    Filed: April 13, 1989
    Date of Patent: July 17, 1990
    Assignee: Eastman Kodak Company
    Inventors: John R. Monnier, Peter J. Muehlbauer
  • Preparation of aldehydes from unsaturated terminal epoxides
    Patent number: 4925986
    Abstract: Crotonaldehyde is produced by contacting 3,4-epoxybutene, i.e. butadiene monoxide, with a halide-containing catalyst such as a hydrogen halide or metal halide. The process is preferably conducted in the vapor phase. Other unsaturated aldehydes can be produced from other unsaturated terminal epoxides.
