Abstract
Sulphuretted hydrogen and an alkaline earth chloride are obtained by heating an alkaline earth sulphate such as barytes, celestine or gypsum with magnesium chloride and a carbonaceous reducing agent such as coal. Alternatively, the coal &c. may be omitted, a higher temperature being then necessary.ALSO:An alkaline-earth sulphate, such as barytes, celestine or gypsum, is heated with magnesium chloride and coal or other carbonaceous reducing-agent. Sulphuretted hydrogen is evolved, and an alkaline-earth chloride and magnesia are produced. The alkaline-earth chloride is leached out, and the magnesia may be dissolved in sulphuric acid. When it is desired to make barium sulphate by treating the barium chloride with sulphuric acid, the hydrochloric acid evolved may be used to convert the magnesia into magnesium chloride so as to make the process cyclic. The alkaline-earth sulphate may be heated with magnesium chloride without a reducing-agent, at a higher temperature, but with inferior yield of alkaline-earth chloride.
