Abstract
541,450. Magnesium sulphate and chloride. OCEAN SALTS (PRODUCTS), Ltd., and ADAMS, B. A. May 24, 1940, No. 9154. [Class 1 (iii)] Magnesium chloride solution prepared from sea water by means of an organic cation exchange material, as described in Specification 536,266, is contacted with an organic cation exchange material having exchangeable hydrogen ions whereby hydrochloric acid is produced and the exchange material is charged with magnesium ions. The latter material is then treated with sulphuric acid to produce magnesium sulphate solution, which is concentrated and crystallized. and to regenerate exchangeable hydrogen ions in the exchange material to make it ready for re-use. The hydrochloric acid from the first stage is contacted with an organic anion exchange material previously treated with an alkali, and thus containing hydroxyl ions, whereby water is produced and the exchange material is charged with chlorine ions. The latter material is then treated with a suspension of magnesium hydroxide, prepared from sea water as described in Specification 535,852, to produce magnesium chloride solution, which is concentrated and crystallized, and to render the exchange material capable of adsorbing further chlorine ions. Specifications 450,308, 450,309, 533,509 and 535,854 also are referred to.
