  A continuous process for the production of an alkyl ester product is described. The process includes the steps of carbonylating ethylene with carbon monoxide in the presence of C1-6 alkanol co-reactant to form the alkyl ester product. The carbonylation takes place in the presence of a catalyst system that includes (a) a bidentate ligand, (b) a catalytic metal selected from a group 8, 9 or 10 metal or a compound thereof, and (c) a sulphonic acid capable of forming an acid alkyl ester with the C1-6 alkanol. The process includes the step of separating the alkyl ester product from a carbonylated crude product stream by treatment effective to vaporizing the alkyl ester product in a single stage flash distillation column and providing a purified alkyl ester product stream separated from the bidentate ligand and catalytic metal.

  A process for the carbonylation of an ethylenically unsaturated compound comprising the step of reacting said compound with carbon monoxide in the presence of a co-5 reactant having a mobile hydrogen atom and a catalyst system is described. The catalyst system is obtainable by combining: (a) a metal of Group 8, 9 or 10 or a suitable compound thereof; (b) a ligand of general formula (I): and c) optionally, a source of anions. The invention is characterised in that the catalyst system includes an enhancer compound comprising an aromatic ring or ring system substituted by at least one hydroxyl group wherein the hydroxyl group pKa at 25° C. is greater than 3.0 and less than 9.1, the said enhancer compound excluding 3-quinolinol. Catalyst systems for use with the enhancer compound are described as are a method of increasing the efficacy of a catalyst system for the carbonylation of ethylenically unsaturated compounds and a method of increasing the rate of carbonylation of an ethylenically unsaturated compound comprising the step of adding such a compound to the reaction.
