Patent number: 7629491Abstract: Disclosed is a hydrocarboxylation process for the production of carboxylic acid from olefins wherein an olefin, water, a Group VIII metal hydrocarboxylation catalyst, an onium salt compound are combined in a reaction zone and contacted with carbon monoxide under hydrocarboxylation conditions of pressure and temperature The process does not require or utilize the addition of a hydrogen halide or an alkyl halide exogenous or extraneous to the hydrocarboxylation process.Type: GrantFiled: June 26, 2006Date of Patent: December 8, 2009Assignee: Eastman Chemical CompanyInventors: Joseph Robert Zoeller, Mary Kathleen Moore

Publication number: 20090247783Abstract: Disclosed is an improved 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, other than the onium salt, such as a hydrogen halide (typically, hydrogen iodide) and/or an alkyl halide (typically, methyl iodide), extraneous or exogenous to the carbonylation process is not fed or supplied to the process. The process can be improved by using a bidentate ligand comprising two functional groups selected from tertiary amines and tertiary phosphines, such as 2,2?-bipyridine and diphosphine derivatives.Type: ApplicationFiled: April 1, 2008Publication date: October 1, 2009Applicant: EASTMAN CHEMICAL COMPANYInventors: Joseph Robert Zoeller, Mary Kathleen Moore

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

Patent number: 6740762Abstract: Disclosed is a process for the preparation of ascorbic acids from 2-keto-hexonic acids or 2-keto-hexonic acid derivatives using alkaline earth silicate catalysts. The process may be carried out in water, alcohols, or in a variety of polar or moderately polar solvents or solvent mixtures and provides for simple workup and purification of ascorbic acid products. The process generates no by-product salts and thus, does not require the steps of neutralization or the handling of salt by-products. The process is particularly suited for the continuous preparation of L-ascorbic acid from 2-keto-L-gulonic acid and its esters.Type: GrantFiled: August 7, 2002Date of Patent: May 25, 2004Assignee: Eastman Chemical CompanyInventors: Joseph Robert Zoeller, Allen Lynn Crain

Patent number: 6683216Abstract: Disclosed is a process for the preparation of amines by continuously feeding a carboxamide, aqueous alkaline hypohalite, and aqueous alkaline hydroxide to a first reaction zone to form a N-halocarboxamide, measuring the concentration of at least one reaction component in the effluent from the first reaction zone, and using the result of that measurement to control the feed rate of at least one of the feed components of to achieve at least 90% conversion of the carboxamide in the first reaction zone. The effluent from the first reaction zone is fed continuously to a second reaction zone where it further reacts to form an aqueous solution of an amine. The effluent from the second reaction zone may be fed continuously to a distillation column. The process is particularly useful for the preparation of cyclopropylamine.Type: GrantFiled: November 6, 2002Date of Patent: January 27, 2004Assignee: Eastman Chemical CompanyInventors: Joseph Robert Zoeller, Norma Lindsey Buchanan, Elizabeth Celia Sharkey, Daniel Latham Terrill, Steven Paul Bellner
