Abstract

120,838. Dutt, E. E., and Dutt, P. C. March 4, 1918. Alumina; arsenious acid; barium, calcium, magnesium, and strontium aluminates; arsenious chloride.-A mixture of calcined clay or bauxite, or both, with calcium or other alkaline-earth chloride, is heated to bright redness in a .stream of arsenious oxide vapour, producing arsenious chloride, which is decomposed by steam into arsenious oxide and hydrochloric acid, and an aluminate. The residue is dissolved in hydrochloric acid and treated with calcium aluminate to precipitate alumina and re-form calcium chloride, which, after the addition of some lime to precipitate the iron, may be used again.
