Abstract
Anhydrous magnesium chloride is prepared by (1) adding magnesium chloride to an agitated aqueous ammonia solution containing not more than 65 weight per cent ammonia, (2) maintaining the ammonia concentration in the reaction mixture at 35 to 65% by weight of the solution throughout the reaction, (3) separating the precipitated magnesium chloride hexammoniate from the reaction mixture and heating it to recover anhydrous magnesium chloride. A soluble ammonium salt, e.g. ammonium chloride, acetate or thiocyanate may be added to the agitated aqueous solution in amounts up to 10% by weight of reaction mixture. The reactor may be operated at 10 DEG to -20 DEG C. or less at atmospheric pressure, or at a temperature in the range 40 DEG to 75 DEG C. and a pressure of 7.1 to 8.5 kg./cm.2. A batch or continuous process may be used.
