PROCESS FOR THE PREPARATION OF ANHYDROUS MAGNESIUM CHLORIDE FROM INORGANIC SALTS

摘要

A process for the preparation of anhydrous magnesium chloride from inorganic salts by means of treatment of salt solution with ammonium carbonate (or carbon dioxide with ammonia) and ammonium chloride in mole ratio to magnesium chloride 1:2:3 (correspondingly) with separation of magnesium carbonate and ammonium carnallite into a sediment at heating to 350 °C with staged separation of water, carbon dioxide, ammonium and formation of anhydrous magnesium chloride.
