Abstract
Production of sodium bicarbonate by the Solvay-soda method, employing a volatile aliphatic amine instead of ammonia, is combined with the oxychlorination of olefins in liquid phase by using the amine hydrochloride side-product of the soda plant as chlorine source in the oxidative regeneration of the spent chlorinating liquid. The chlorinating liquid contains iodine and copper chloride or iron chloride and on regenerating the spent liquid the amine is recovered in the vapor phase and recycled to the soda plant.
