Dennis G. Morrell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6608155
    Abstract: Supported metal halides and metal halide solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomer, C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5° C. to 170° C. can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerization catalysts since the acid sites are an integral part of the solid. The solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or by-products.
    Type: Grant
    Filed: January 7, 1998
    Date of Patent: August 19, 2003
    Assignee: Eastman Chemical Resins, Inc.

  • Patent number: 6281309
    Abstract: Fluorinated solid acids and supported fluorinated solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomer, C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the fluorinated solid acid catalyst and/or supported fluorinated solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5° C. to 170° C. can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerization catalysts since the acid sites are an integral part of the solid. The fluorinated solid acid catalysts and supported fluorinated solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or by-products.

  • Patent number: 6133386
    Abstract: Metal oxide solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomer (e.g., styrene based monomers), C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5.degree. C. to 170.degree. C. can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerization catalysts since the acid sites are an integral part of the solid. The solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or by-products.

  • 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.

  • 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.
