ABSTRACT:
A process for the carbonylation of a carbonylatable reactant having a carbonylatable moiety having at least two carbon atoms and/or a reactive derivative thereof which process comprises contacting said carbonylatable reactant and/or a reactive derivative thereof with carbon monoxide in a liquid reaction composition in a carbonylation reactor characterized in that the liquid reaction composition comprises: (a) an iridium catalyst, (b) a halide, (c) at least a finite concentration of water, (d) a carbonylatable reactant having a carbonylatable moiety having at least two carbon atoms and/or a reactive derivative thereof and (e) as promoter, at least one of ruthenium and osmium.
