Patent number: 9988329Abstract: A transfer-hydrogenation process for preparing a carbonyl compound and an alcohol compound comprises the steps of (a) contacting a first carbonyl compound with a first alcohol compound in the presence of a transfer-hydrogenation catalyst in a first reaction zone at conditions effective to form a second carbonyl compound from the first alcohol compound and a second alcohol compound from the first carbonyl compound, and (b) removing the second carbonyl compound from the first reaction zone during step (a). The first carbonyl compound is a saturated aldehyde or ketone, or an ?,?-unsaturated aldehyde or ketone. The first alcohol compound is a primary or secondary alcohol. The second alcohol compound is ?,?-saturated. The transfer-hydrogenation catalyst includes a Group 8 to 11 metal. This process is useful for preparing and higher value alcohols, such as butanol or 2-ethylhexanol, from the corresponding carbonyl compounds by engaging lower alcohol (C2-C4) feedstocks instead of hydrogen (H2).Type: GrantFiled: February 8, 2017Date of Patent: June 5, 2018Assignee: Eastman Chemical CompanyInventors: Mesfin Ejerssa Janka, Robert Thomas Hembre, Scott Donald Barnicki, Robert Scott Huss, Xiaopeng Shan, Stephanie Rollins Testerman, Timothy Alan Upshaw, Dewey Wayne Fuller, Jr.

Patent number: 9505692Abstract: The invention provides improved energy content in and shaft power recovery from off-gas from xylene oxidation reactions while at the same time minimizing wastewater treatment cost. More shaft power is produced using off-gas than is required to drive the main air compressor, even with preferred, relatively low oxidation temperatures. Simultaneously, an amount of wastewater greater than byproduct water from oxidation of xylene is kept in vapor form and treated along with off-gas pollutants in a self-sustaining (self-fueling) gas-phase thermal oxidative destruction unit. Optionally, off-gas is combined from multiple xylene oxidation reactors, comprising primary and/or secondary oxidation reactors and forming TPA and/or IPA. Optionally, air compressor condensate and caustic scrubber blowdown are used in a TPA process or as utility water, effectively eliminating normal flow of liquid wastewater effluent from a TPA plant.Type: GrantFiled: September 9, 2009Date of Patent: November 29, 2016Assignee: Grupo Petrotemex, S.A. de C.V.Inventors: Raymond Elbert Fogle, III, Ronald Buford Sheppard, Timothy Alan Upshaw, Alan George Wonders
