Technology Process of aluminum maltolate

There total 2 articles about aluminum maltolate which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 86.0%

Maltol (118-71-8) + aluminum(III) nitrate nonahydrate → tris(3-hydroxy-2-methyl-4H-pyran-4-onato)aluminium(III) (103616-17-7,23058-19-7)

Guidance literature:

In water; with const. stirring maltol and Al(NO3)3*9H2O was added to water, pH was adjused to 8.3, mixt. was heated to 65°C; soln. was filtered, washed with acetone, dried in vac.; elem.anal.;

Reference yield:

Maltol (118-71-8) + aluminium(III) ion (22537-23-1) → tris(3-hydroxy-2-methyl-4H-pyran-4-onato)aluminium(III) (103616-17-7,23058-19-7) + Al2(OH)2{C5H2O(O)(O)CH3}2(2+) + Al{C5H2O(O)(O)CH3}(2+) + Al{C5H2O(O)(O)CH3}2(1+)

Guidance literature:

With NaCl; In water; potentiometric study of the formation of Al{C5H2O(O)(O)CH3}(2+), Al{C5H2O(O)(O)CH3}2(1+); Al{C5H2O(O)(O)CH3}3 and Al2(OH)2{C5H2O(O)(O)CH3}2(2+) in an aq. NaCl soln. from Al(3+) and maltol;
