    Abstract: Improvement in the process of producing carboxylic acid esters or salts involving contacting a halogen alkyl compound with carbon monoxide and a basic substance in the presence of a carbonylation catalyst for carbonylation of the halogen alkyl and production of the corresponding ester or salt of the basic substance. The improvement involves performing the contacting in a reaction vessel, circulating a liquid mass of the halogen alkyl, basic substance and carbonylation catalyst through the vessel and maintaining a carbon monoxide atmosphere in the vessel, injecting the circulating liquid mass into the vessel with a nozzle to spray the liquid mass into the vessel and intimately mixing the liquid mass with carbon monoxide in the nozzle for injection of carbon monoxide into the vessel with the sprayed liquid mass.
