Filed:
Dec 12, 1974
Appl. No.:
5/531946
Inventors:
Denis Forster - University City MO
Arnold Hershman - Creve Coeur MO
Assignee:
Monsanto Company - St. Louis MO
International Classification:
C07C 5154
US Classification:
260546
Abstract:
The present invention relates to an improved process for the preparation of organic carboxylic acid anhydrides, specifically by the reaction of ethylenically unsaturated compounds having 2 to 30 carbon atoms with carbon monoxide and carboxylic acids or substances which yield carboxylic acids under reaction conditions at a temperature of 50. degree. C to 300. degree. C and a partial pressure of carbon monoxide of from 1 to 200 atm. in the presence of a catalyst composition essentially comprised of 1. a cobalt or nickel compound, and 2. an iodide component subject to the conditions that the atomic ratio of iodide to cobalt or nickel is from 1:1 to 300:1, 3. a catalyst preserver or regenerator component selected from the group consisting of hydrogen or a compound capable of giving rise to hydrogen under the reaction conditions. The process is particularly suited to the production of propionic anhydride.

Assignee:
BP Chemicals Limited - London
International Classification:
C07C 5110
C07C 5114
US Classification:
562517
Abstract:
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.
