Abstract
The present invention provides a process for the preparation of an improved nickel-containing catalyst suitable for the conversion of alcohols to the corresponding carboxylic acid which involves combining a nickel compound, an N-containing organic compound and an iodine promoter, bringing the combination in contact with an alcohol in the presence of carbon monoxide and subjecting the mixture to a temperature and pressure sufficient to initiate carbonylation of the alcohol. The process is characterized in that the N-containing organic compound is isoquinoline or a derivative thereof.
