Abstract

328,688. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Feb. 5, 1929. Aluminium fluoride, anhydrous or hydrated, is prepared by treating alumina, or hydrated alumina with gaseous hydrofluoric acid, obtained, for instance, from fluor spar and sulphuric acid. In place of gaseous hydrofluoric acid, a mixture of gaseous hydrofluoric acid and gaseous hydrochloric acid, such as obtained in the process of Specification 328,211 may be employed, only aluminium fluoride being formed. The amount of water in the product depends on the temperature at which the reaction is carried out, which in any case should not be higher than about 400‹ C. At 100‹ C., the water content is about 6 per cent, decreasing to practically zero at 200‹ C. and higher. Similar results are obtained when the reaction is carried out at room temperature, and the temperature raised towards the end of the operation.
