METHOD OF ALUMINIUM BASIC CHLORIDE PRODUCING (VARIANTS)

摘要

FIELD: inorganic chemistry and technology. SUBSTANCE: invention relates to method of chloroaluminium-containing coagulating agents producing. Method involves chemical dissolving aluminium-containing raw in 5-15% hydrochloric acid solution or in mixture of hydrochloric acid and natural bischofite at ratio = (0.3-0.9):(0.1-0.7). Processes of dissolving and hydrolysis were carried out at 90-95 C due to aluminium heat dissolving without additional heat supply. The used aluminium-containing raw - aluminium alloys containing iron (0.25-10.1%). Under these conditions the rate of aluminium dissolving is increased significantly due to arising galvanic pair iron-aluminium. EFFECT: improved method of producing.
