METHOD OF PRODUCING ALUMINIUM OXYCHLORIDE Russian patent published in 2016 - IPC C01F7/56

Abstract RU 2589164 C1

FIELD: chemistry.

SUBSTANCE: invention relates to chemical engineering, particularly to a method of producing (main chloride) aluminium oxychloride. Method of producing aluminium oxychloride by processing of aluminium hydroxide hydrochloric acid while heating, characterised by that before heating added inorganic compound-alkali metal silicate or silicic acid in amount of 0.005-0.8 mol SiO₂ on 1 kg of Al(OH)₃.

EFFECT: technical result is production of aluminium oxychloride with high molar ratio of aluminium to chlorine, up to 2:1, and basicity to 83 %.
