Abstract
271,816. R³tgerswerke - Akt. - Ges. May 31, 1926, [Convention date]. Hydrofluoric acid; hydrofluosilicic acid. - Hydrofluoric acid and silicon fluoride evolved by treating natural fluorides with acids, are absorbed by an aqueous solution or suspension which will convert the gaseous mixture into salts. The gases may act upon a suspension of alumina, kaolin or of substances containing alumina, aluminium fluoride being obtained with precipitation of silicic acid hydrate. The aluminium fluoride may be purified by crystallization or by further treatment with alumina &c. When absorbed by a solution of soda or a sodium salt, sodium fluoride and sodium fluosilicate are formed and can be worked up in known manner. The process can be carried out in wooden vessels or in trickling towers.
