Process for the extraction of an organic liquid containing an organic nitrogen-containing base from a water suspension of mineral particles, and process for the production of alkali 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.
