FIELD: chemistry.SUBSTANCE: method of obtaining aluminium oxychlorides includes processing of thermochemically activated aluminium hydroxide with water solution of hydrochloric acid with heating. Thermochemically activated aluminium hydroxide is preliminarily subjected to hydration with acid solution with oxygen-containing anion: nitric, sulphuric, formic, acetic oxalic, with acidity modulus 0.01-0.50 at temperature 50-95°C. After hydration sediment is separated, hydrochloric acid solution is added to it with supporting pH from 4 to 6 and temperature 50-98°C. Obtained aluminium oxychlorides are separated in form of solutions or solid substances.EFFECT: invention makes it possible to simplify obtaining highly basic aluminium oxychlorides, eliminating aluminium hydrochloride milling.7 cl, 2 tbl, 5 ex |
