Patent number: 5117046Abstract: Alkylidene diesters such as ethylidene diacetate are produced by reacting an ether and/or an ester under substantially anhydrous conditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound and a halogen component at a temperature in the range from 125.degree. to 300.degree. C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/cm.sup.2. When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques. Since one mole of acetic acid is also produced in the synthesis of the diacetate, the invention makes possible an overall process for the production of vinyl acetate which produces acetic acid rather than consumes it.Type: GrantFiled: June 30, 1975Date of Patent: May 26, 1992Assignee: Monsanto CompanyInventors: Frank E. Paulik, Robert G. Schultz

Patent number: 5003104Abstract: This invention involves a process for the carbonylation of a carbonylatable reactant, e.g., an alkyl ester, a dialkyl ether or mixtures thereof by reacting the same with carbon monoxide. The process comprises effecting the carbonylation in the presence of a solution of a catalyst system containing a rhodium compound, an iodide and a lithium component at a temperature of from 50.degree. C. to 400.degree. C. at a carbon monoxide partial pressure of 1 psig to 15,000 psig. Hydrogen may also be present. The invention also concerns a carbonylation catalyst system effective for the addition of carbon monoxide to a carbonylatable reactant which comprises a solution containing as essential components a rhodium containing active component, an iodide and a lithium component.Type: GrantFiled: October 31, 1988Date of Patent: March 26, 1991Assignee: BP Chemicals LimitedInventors: Frank E. Paulik, Arnold Hershman, Walter R. Knox, Robert G. Schultz, James F. Roth

Patent number: 4810821Abstract: Alkylidene diesters such as ethylidene diacetate are selectively produced in high yields by reacting an ether and/or an ester under substantially anhydrous conditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound, a halogen component, a palladium cocatalyst and a promoter component which is an agent for liberation of carboxylic acid anions. The process is carried out in the liquid phase in a solvent comprising a carboxylic acid at a temperature in the range of 150.degree. to 190.degree. C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/cm.sup.2 and a carbon monoxide/hydrogen mole ratio of 6:1 to 1:2 for the ester reaction and 10:1 to 1:2 for the ether reaction. When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques.Type: GrantFiled: May 31, 1985Date of Patent: March 7, 1989Assignee: Monsanto CompanyInventors: Frank E. Paulik, Robert G. Schultz

Patent number: 4792620Abstract: A catalyst system having high activity and selectivity to carbonylation products comprises a rhodium-containing catalytically active component and a halogen-containing promoter component, the halogen being selected from the group consisting of bromine, iodine, bromide compounds, and iodide compounds.Type: GrantFiled: March 3, 1987Date of Patent: December 20, 1988Assignee: BP Chemicals LimitedInventors: Frank E. Paulik, Arnold Hershman, Walter R. Knox, James F. Roth

Patent number: 4733006Abstract: The present invention provides for an improved process wherein an olefin, an alcohol, or an ester, halide or ether derivative of said alcohol is reacted with carbon monoxide in a liquid phase in the presence of a catalyst system that contains (a) a rhodium component, and (b) and iodine or bromine component. By passing at least a portion of the liquid reaction mass from the reaction zone to a separation zone of substantially lower CO partial pressure, at least a portion of the carbonylation products, as well as unreacted carbon monoxide, inert gases and unreacted olefin, alcohol or alcohol derivatives are vaporized and can be withdrawn from the separation zone. Precipitation of the rhodium catalyst under carbon monoxide deficient conditions is prevented or retarded by addition to the carbon monoxide deficient zones of the system of a catalyst stabilizer which is a germanium (IV) compound, an alkali metal compound, and mixtures thereof.Type: GrantFiled: August 18, 1983Date of Patent: March 22, 1988Assignee: Monsanto CompanyInventors: Thomas C. Singleton, Frank E. Paulik
