PROCESS FOR OBTAINING A WATER-INSOLUBLE NITROGENIC ORGANIC BASE OR DEPARTURE OF AQUEOUS SOLUTION OF ALKALI METAL BICARBONATE AND CHLORHYDRATE THEREOF AND PROCESS FOR PRODUCING SODIUM BICARBONATE

摘要

Process for the production of a water-insoluble nitrogeneous organic base, from an aqueous solution of alkali metal bicarbonate and the base hydrochloride, according to which the solution (11) is treated with a complement of the base hydrochloride (12), and the resultant liquid (18) is treated with a basic agent (30) capable of decomposing the hydrochloride. The invention is applied to the regeneration of the amine in the process for the manufacture of sodium bicarbonate by the amines method.
