<p>A process for the production of oxygenated organic compounds comprises contacting at elevated temperature carbon monoxide in a carbonylation reactor with a liquid reaction composition comprising (a) (i) at least one olefinically unsaturated compound and, optionally (ii) at least one alcohol and/or a reactive derivative thereof, (b) an iridium catalyst, (c) a halide co-catalyst, (d) at least a finite concentration of water, and (e) as promoter, at least one of (i) cadmium, (ii) mercury, (iii) zinc, (iv) gallium, (v) indium, (vi) tungsten, and (vii) rhenium provided that in the absence of an alcohol and/or a reactive derivative thereof (A) in the presence of promoters (i) to (vi) water is present in an amount less than 3% by weight based on the weight of the liquid reaction composition, and (B) in the presence of promoters (i) to (vii) the partial pressure of carbon monoxide is less than 5 bar.</p> |
