BICARBONATE GRANTS SEPARATION OF A ALKALINE METAL OF A LIQUID CHLORIDRATE FILM OF A ROTATED ORGANIC BASE ABSORBED TO ITS SURFACE AND PROCESS FOR THE PRODUCTION OF BICARBONATE OF A METAL ALKALINE

摘要

To separate particles of alkali metal bicarbonate (11) from a liquid film of hydrochloride of a nitrogenous organic base adsorbed at their surface they are dispersed in an aqueous bath (14) and the resulting aqueous suspension is subjected successively to a turbulence (13) and then to sedimentation (16). The process applies to particles of sodium bicarbonate obtained by the amine process. IMAGE
