Kelley Margaret Moran 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).

  • Reactive distillation of a carboxylic acid and a glycol
    Patent number: 9114328
    Abstract: Disclosed is a process for producing glycolate ester oligomers. The process comprises reacting ethylene glycol and glycolic acid to produce a stream of glycolate ester oligomers and glycolic acid oligomers while simultaneously removing water. The stream of glycolate ester oligomers and glycolic acid oligomers has a low concentration of water and glycolic acid-ends, and thus is useful in a subsequent hydrogenation reaction to produce ethylene glycol.
    Type: Grant
    Filed: May 16, 2012
    Date of Patent: August 25, 2015
    Assignee: Eastman Chemical Company
    Inventors: Daniel Latham Terrill, Kelley Margaret Moran, Stephen Neal Falling
  • Hydrocarboxylation of aqueous formaldehyde using a dehydrating recycle stream to decrease water concentration
    Patent number: 9040748
    Abstract: Disclosed is a process for the production and purification of glycolic acid or glycolic acid derivatives by the carbonylation of aqueous formaldehyde. The water in the hydrocarboxylation zone is reduced via reaction with the ester bonds in a recycle stream comprising glycolic acid oligomers and/or methyl glycolate oligomers.
    Type: Grant
    Filed: June 8, 2012
    Date of Patent: May 26, 2015
    Assignee: Eastman Chemical Company
    Inventors: Mesfin Ejerssa Janka, Scott Donald Barnicki, Robert Thomas Hembre, Kelley Margaret Moran, Stephen Neal Falling
  • Hydrocarboxylation of formaldehyde in the presence of a higher order carboxylic acid and heterogeneous catalyst
    Patent number: 8829234
    Abstract: Disclosed is a process for the production and purification of glycolic acid or glycolic acid derivatives by the carbonylation of formaldehyde in the presence of a solid acid catalyst and a carboxylic acid. This invention discloses hydrocarboxylations and corresponding glycolic acid separations wherein the glycolic acid stream is readily removed from the carboxylic acid and the carboxylic acid is recycled.
