Process for the preparation of carboxylic acids from aliphatic alcohols |
| abstract |
The present invention provides an improved process for the production of carboxylic acids by the carbonylation of alcohol. The process involves contacting an alcohol with carbon monoxide in the presence of a nickel compound, a heterocyclic organic compound and an iodide promoter to produce the corresponding carboxylic acid. The improvement relates to the use of heterocyclic organic compound as a promoter containing at least two heteroatoms of which at least one is selected independently from S or N, which provides an inexpensive and stable catalyst system. |
