Process for the hydrocarbonylation and/or carbonylation of alkyl carboxylates

Abstract

Abstract Alkyl carboxylates are hydrocarbonylated and/or carbonylated with carbon monoxide and hydrogen, in an aqueous medium, and in the presence of a catalytically effective amount of a catalyst system comprising (i) ruthenium, (ii) cobalt, (iii) at least one iodine-containing promoter, and (iv) chromium. The subject hydrocarbonylation/carbonylation is admirably well suited, e.g., for the preparation of acetaldehyde, ethanol, ethyl acetate and acetic acid, especially from a methyl carboxylate.
