Patent number: 9718754Abstract: Disclosed is a process for the reductive carbonylation of a low molecular weight alcohol to produce the homologous aldehyde and/or alcohol. The process includes conducting the reaction to produce the aldehyde in the presence of a single component catalyst complex composed of cobalt, an onium cation and iodide in a ratio of 1:2:4 without additional promoters. A ruthenium co-catalyst is used in the production of the homologous alcohol. The reductive carbonylation reaction does not require an additional iodide promoter and produces a crude reductive carbonylation product substantially free of methyl iodide.Type: GrantFiled: May 13, 2016Date of Patent: August 1, 2017Assignee: Eastman Chemical CompanyInventors: Jonathan Michael Penney, David William Norman, Andrew James Vetter

Patent number: 8785686Abstract: Disclosed is a process for the extractive recovery of an acid catalyst from an aqueous mixture of glycolic acid with an extraction solvent comprising a tertiary amine or an onium carboxylate compound, a modifier, and a diluent. The acid catalyst, which can comprise strong acids such as sulfuric acid, alkyl sulfonic acids, and fluoroalkyl sulfonic acids, can be recovered by back extraction with aqueous formaldehyde and recycled to a process for the preparation of glycolic acid by the acid-catalyzed carbonylation of formaldehyde. Also disclosed is a process for the preparation of glycolic acid by the acid-catalyzed hydrocarboxylation of formaldehyde.Type: GrantFiled: March 27, 2012Date of Patent: July 22, 2014Assignee: Eastman Chemical CompanyInventors: Scott Donald Barnicki, Stephen Neal Falling, Jeffrey Scott Kanel, Robert Sterling Kline, Peter Borden Mackenzie, Andrew James Vetter

Patent number: 7582792Abstract: Disclosed is a carbonylation process for the production of carboxylic acids, carboxylic acid esters and/or carboxylic acid anhydrides wherein a carbonylation feedstock compound selected from one or more organic oxygenates such as alcohols, ethers, and esters is contacted with carbon monoxide in the presence of a carbonylation catalyst and one or more onium compounds. The carbonylation process differs from known carbonylation processes in that a halide compound such as a hydrogen halide, typically hydrogen iodide, and/or alkyl halide, typically methyl iodide, extraneous or exogenous to the carbonylation process is not fed or supplied separately to the process.Type: GrantFiled: June 15, 2006Date of Patent: September 1, 2009Assignee: Eastman Chemical CompanyInventors: Joseph Robert Zoeller, Mary Kathleen Moore, Andrew James Vetter

Patent number: 7498469Abstract: Glycoaldehyde (GA) is prepared via self condensation of formaldehyde in the presence of a n-heterocyclic carbene to generate GA and glyceraldehyde (GlyAld) with selectivity toward forming the GA. The carbene is generated in situ by the addition of a base to the salt form of the catalyst. Selectivity is controlled by tuning the active site of the catalyst, either sterically and/or electronically.Type: GrantFiled: November 7, 2007Date of Patent: March 3, 2009Assignee: Eastman Chemical CompanyInventors: Andrew James Vetter, Mesfin Ejerssa Janka, Joseph Robert Zoeller
