ABSTRACT:
Substantially anhydrous magnesium chloride is prepared through the chlorination of a hydrated magnesium chloride by melting the hydrated chloride, feeding that molten material to a bed of carbonaceous material so that it flows downwardly therethrough and simultaneously feeding a mixture of chlorine and air to the bed of carbonaceous material so that it flows upwardly therethrough countercurrent to the molten material, until magnesium chloride of the desired state of purity is obtained, and the purified magnesium chloride is then recovered.
