Patent number: 9227902Abstract: An alcohol such as methanol is reacted with carbon monoxide in a liquid reaction medium including a catalyst, an alkyl iodide such as methyl iodide, alkyl acetate such as methyl acetate in specified proportions, an additive, and an effective amount of water, where the additive increases an ionic character of the hydrogen iodide bond and the effective amount of water is sufficient to facilitate carboxylic acid release after carbonylation at the catalyst and to reduce anhydride formation. The present reaction system not only provides an acid product at water levels considerable below levels currently used, but also provides unexpected reaction rates and unexpected high catalyst stability.Type: GrantFiled: April 4, 2014Date of Patent: January 5, 2016Assignee: Pretium Ventures AA, LLCInventors: Ronnie M.

Patent number: 6022823Abstract: An improved process for producing high activity and high selectivity supported palladium-gold catalysts is provided. The process involves calcining the support impregnated with a palladium salt and gold salt in a non-reducing atmosphere and at a temperature ranging from 100.degree. C. to 600.degree. C. prior to reducing the metals. Catalysts of the invention are useful for the production of vinyl acetate in the vapor phase by reaction of ethylene, acetic acid and oxygen.Type: GrantFiled: October 31, 1996Date of Patent: February 8, 2000Assignee: Millennium Petrochemicals, Inc.Inventors: Steven M.

Patent number: 5336802Abstract: A method for pretreatment of a palladium-gold catalyst useful in the synthesis of vinyl acetate. A virgin catalyst, following reduction to the metallic palladium and gold, is first heated at elevated temperatures in the presence of an oxidizing agent such as air. The oxidizing agent is withdrawn and an inert gas such as nitrogen is introduced. The catalyst is heated again at a temperature up to 500.degree. C. in the presence of a reducing agent such as hydrogen or ethylene. Improvements in selectivity and yield are obtained.Type: GrantFiled: May 21, 1993Date of Patent: August 9, 1994Assignee: Quantum Chemical CorporationInventors: David W. Smith, Ronnie M.

Patent number: 5237097Abstract: A process is disclosed for the carbonylation of an organic compound selected from the group consisting of an olefin, an alcohol, an acid and an ester. In this process the organic compound is reacted with carbon monoxide in the presence of a Group VIII metal-containing catalyst. The liquid carbonylation product solution of this reaction is conveyed to a separation zone maintained at a lower total pressure than is the pressure in the reaction zone. Simultaneously with the conveyance of the liquid product solution to the separation zone is the introduction therein of a carbon monoxide-containing gaseous stream, the carbon monoxide therein contributing a partial pressure of up to 30 psia of the total pressure in said separation zone. A portion of the liquid carbonylation product solution is flashed and removed from the separation zone. The unflashed liquid carbonylation product solution is recycled back into the reaction zone.Type: GrantFiled: December 22, 1992Date of Patent: August 17, 1993Assignee: Quantum Chemical CorporationInventors: David W. Smith, Ronnie M. Hanes
