METHOD FOR THE EXTRACTION OF AN ORGANIC LIQUID CONTAINING AN AZOTATED ORGANIC BASE FROM AN AQUEOUS SUSPENSION OF MINERAL PARTICLES, AND METHOD FOR PRODUCING ALKALINE METAL BICARBONATE.

摘要

Extraction of an organic liquid containing a water-insoluble nitrogenous organic base from an aqueous slurry of particles of inorganic material (20), according to which an inert gas (23) is circulated through the slurry. The process applies to the extraction of an amine present in an aqueous calcium chloride solution containing particles of inorganic material. IMAGE
