Abstract
A process is presented in which anhydrous soda is crystallized and worked up to produce anhydrous soda crystals with a bulk density from 1300 to 1600 kg/m3. The process is characterized in that a solvent is used that allows the crystals to be formed and handled at atmospheric pressure in the presence of water without the monohydrate of soda being formed.
