"Process for evaporation tos aluminum trihalides *

The rorliegende invention shall look custody to the evaporation of Aluisiniuatrihalogeniden, OIOS among which are for the present purpose but only Aluainiuistriehlorid and Aluainiuatribroaid su ντ ·. The invention is of particular importance for a process as well as a Torrichtang sur evaporation τοη AluBlnluatrlcblorld from the solid state »also for Yerfearen in which such an evaporation process is necessary» to purify gaseous8 Aluadniuatrichlorid * and «was in connection with the subhalide reetillation By way of extraction of τοη aluminum from a metal containing aluainiuah

The evaporation of aluminum trichloride (AlCl ₅ ) from a "non-gaseous state" brings about unusual difficulties due to the special physical properties of this

keiten sit eich. Although geefoiery Aluainiuatrioblorid «ti · & ·« solid · »state · are replaced by direct · sublimation, while a measure of particles of solid Aluainluatrlchloride ▼ is obtained from the outside, such a · sublimation has an undesirably low efficiency From the point of view of the "en" glever consumption and the Yerdaapfungesiffer, because the heat transfer in solid aluminum chloride is low. Evaporation from the purely liquid state can only take place under special conditions of increased temperature and increased pressure. works above the so-called fripel point. The latter method requires the use of W & ra, which is carried out from the outside} but the non-volatile residues tend to collect in the form of a powder or a crust over the hot surface, whereby the w * r » - We prevent the transition from the hot surface to the liquid with a simultaneous decrease in the evaporation rate and little utilization of the suggested water energy.

The evaporation τοη Aluainiuatrichlorid from a non-fragrant Condition · is important for other commercial operations »Am such a case, in which» a light · and economical yerdaapfen goose is particularly desirable, results eich la Zuawtssenhang old AluainiUB purified from the nucleus of raw aluminum-containing alloys or of others impure metals containing aluainlua after the subbalogenide distillation process. This last procedure is used the currently preferred rraxia dl · concerning ugation old gaseous "aluminium chloride, among other things, i.e. it is fiery aluminum chlorine in a heated two-part of the alloy b ·! a temperature range, from 1000 - 1400 ° In a
