Process for obtaining a water-insoluble organic NITROGEN BASE OF AN OUTGOING aqueous solution of alkali metal hydrochloride AND SAID BASE AND METHOD 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.
