Abstract

Process for manufacturing sodium carbonate crystals heptahydrate or decahydrate, by cooling an aqueous solution containing sodium carbonate, characterized in that the cooling is carried out by direct contact of the solution with an organic cooling liquid, practically immiscible with water, inert with respect to the solution, and whose vapor tension at the chosen crystallization temperature is close to atmospheric pressure.
