Epoxide Stabilization Of Fluorophosphite-Metal Catalyst System In A Hydroformylation Process
US Patent:
6693219, Feb 17, 2004
Filed:
May 15, 2002
Appl. No.:
10/145922
Inventors:
Thomas Allen Puckette - Longview TX
Ginette Struck Tolleson - Longview TX
Thomas James Devon - Longview TX
Ginette Struck Tolleson - Longview TX
Thomas James Devon - Longview TX
Assignee:
Eastman Chemical Company - Kingsport TN
International Classification:
C07C 4549
US Classification:
568454, 558 71, 556 2, 556 13, 502161
Abstract:
A process for stabilizing a fluorophosphite ligand in a hydroformylation reaction mixture having an -olefin, hydrogen, carbon monoxide and a catalyst composition having a combination of a rhodium containing compound and one or more fluorophosphite compounds having the general formula: wherein R and R are hydrocarbyl radicals which contain a total of up to about 40 carbon atoms, the process includes the step of adding to the reaction mixture an epoxide in a sufficient amount to reduce the degradation of the fluorophosphite ligand.
Process For The Preparation Of Glycolaldehyde
US Patent:
7420093, Sep 2, 2008
Filed:
Sep 12, 2007
Appl. No.:
11/854210
Inventors:
Thomas Allen Puckette - Longview TX, US
Thomas James Devon - Longview TX, US
Thomas James Devon - Longview TX, US
Assignee:
Eastman Chemical Company - Kingsport TN
International Classification:
C07C 45/50
US Classification:
568454, 568458
Abstract:
Disclosed are processes for the preparation of glycolaldehyde in which formaldehyde is contacted with carbon monoxide and hydrogen in the presence of a rhodium catalyst and a solvent containing at least one N,N-dihexylbutyramide. The glycolaldehyde product is recovered by extraction with water. The process provides high selectivity to glycolaldehyde and efficient separation of hydroformylation products from the solvent and rhodium catalyst.
Simplified Process To Prepare Polyolefins From Saturated Hydrocarbons
US Patent:
2007024, Oct 25, 2007
Filed:
Apr 19, 2006
Appl. No.:
11/406705
Inventors:
Jeffrey Vanderbilt - Longview TX, US
Thomas Devon - Longview TX, US
Kenneth Dooley - Longview TX, US
Thomas Devon - Longview TX, US
Kenneth Dooley - Longview TX, US
International Classification:
C08F 210/00
C08F 4/44
C08F 4/44
US Classification:
526160000, 526348000
Abstract:
A simplified process for preparing polyolefins from saturated hydrocarbons is provided. The process involves partial and selective dehydrogenation of a saturated hydrocarbon in the presence of oxygen to form an olefin, unreacted hydrocarbon, and water, and optionally other by-products and oxygen. The water, other by-products (if present), and oxygen (if present) are separated from the olefin and unreacted hydrocarbon. No other separation is performed. The olefin and unreacted hydrocarbon are polymerized in the presence a polymerization catalyst or initiator to make polyolefin. Solid polyolefin is separated from unreacted hydrocarbon, which is recycled to the dehydrogenation reaction.
Production Of Hydroxy Ether Hydrocarbons By Vapor Phase Hydrogenolysis Of Cyclic Acetals And Ketals
US Patent:
2012033, Dec 27, 2012
Filed:
Jun 24, 2011
Appl. No.:
13/168274
Inventors:
Thomas James Devon - Longview TX, US
Damon Ray Billodeaux - Longview TX, US
Damon Ray Billodeaux - Longview TX, US
Assignee:
EASTMAN CHEMICAL COMPANY - Kingsport TN
International Classification:
C07C 41/14
US Classification:
568678
Abstract:
A vapor phase hydrogenolysis reaction to convert cyclic acetal compounds and/or cyclic ketal compounds in the presence of hydrogen to their corresponding hydroxy ether hydrocarbon reaction products using a supported noble metal catalyst. The hydrogenolysis reaction can be carried out in the vapor phase and in the absence of a polyhydroxyl hydrocarbon co-solvent.

Abstract:
Catalyst compositions of palladium supported on alumina or zirconium oxide supports having low or no silicon dioxide contents and having a specific surface area or modified with alkali, alkaline earth, or phosphine oxide compounds are selective in a vapor phase hydrogenolysis reaction to convert cyclic acetal compounds and/or cyclic ketal compounds in the presence of hydrogen to their corresponding hydroxy ether hydrocarbon reaction products.
