FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing tris(8-hydroxyquinolinate)aluminium. Method involves heating aluminium metal powder in an aqueous solution of a base while stirring until intense gas release begins, adding 8-hydroxyquinoline (HQ) in the aqueous solution of the same base with molar ratio Al:HQ = 1:3. Obtained solution is heated and the boiling point is maintained for 60 minutes with constant stirring at a rate of not less than 300 rpm. Obtained precipitate of tris(8-hydroxyquinolinate)aluminium is filtered, washed with water and dried at temperature of 120 °C in an argon atmosphere, after which the obtained precipitate is recrystallised from chloroform.
EFFECT: development of technologically simple and cheap method of obtaining high-purity tris(8-hydroxyquinolinate)aluminium in considerable volumes.
