Abstract: A process for the production of propionic acid which comprises the reaction of ethylene with carbon monoxide and water in the presence of a nickel carbonyl complex at a temperature of from 250 DEG to 320 DEG C in the liquid phase and at a pressure of from 100 to 300 atmospheres in a vertical cylindrical reaction zone, a gaseous zone being maintained at the upper end of the reaction zone and a bottom zone being maintained at the lower end of the reaction zone which is not in communication with said reaction zone over the entire cross section.
