METHOD FOR PRODUCING ESPECIALLY PURE PURE ANALYLUM CHLORIDE

摘要

FIELD: chemistry.SUBSTANCE: obtaining of aluminium chloride is carried out by reacting gaseous hydrogen chloride and metallic aluminium in a reactor made of an inert material. Aluminium chloride vapours are introduced to the cooled surface, which is the inner surface of plastic fluoroplastic pipes capable of elastic deformation. To remove the crystals of aluminium chloridefrom the inner pipe surface, a vibration source or a source of shock deformation of periodic or continuous removal of the crystals of aluminium chloride from the inner pipe surface are fed to the outer surface of the fluoroplastic pipes. Ultra-pure anhydrous aluminium chloride can be used as a catalyst for the cracking of petroleum products, as well as in organic and inorganic syntheses.EFFECT: increasing the purity of the final product by eliminating the mechanical process of removing crystallized aluminium chloride by scraping devices.2 dwg, 2 ex
