Abstract

300,184. Mond, A. L., (I. G. Farbenindustrie Akt.-Ges.). Aug. 4, 1927. Hydrochloric acid; sodium bicarbonate.-Clay, phonolite, leucite, &c. are treated with sulphuric acid, or a mixture of sulphuric and hydrochloric acids. After separating insoluble matter, the solution is evaporated with an amount of sodium chloride equivalent to the sulphuric acid, and the residue is heated to 700‹ C., preferably in a rotary furnace in which the materials and the heating gases pass in the same direction. Hydrochloric acid is evolved. The sintered product is heated to 1000‹ C. with carbon to produce sodium sulphide, sodium aluminate and some soda. The product is lixiviated. Some of sodium sulphide may be separated by crystallization, and alumina is precipitated by treatment with sulphuretted hydrogen or carbon dioxide, or a mixture of these gases. Further quantities of sodium sulphide may be separated by crystallization. The mother liquor, or the liquor before separation of sodium sulphide may be treated with carbon dioxide to separate sodium bicarbonate. If the clay &c. has been treated mainly with hydrochloric acid, alkali sulphate may be added to the sintered product, and if only small amounts of hydrochloric acid have been used, bauxite may be added in order that the sintered mass may contain about equimolecular proportions of alumina and sodium sulphate.
