    摘要: 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.

    摘要: 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as unreacted carbon monoxide, inert gases and unreacted olefin, alcohol or alcohol derivatives are vaporized and can be withdrawn from the separation zone.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.
