| Abstract: | The reaction of aluminium(III) with kojic acid was investigated in the range ofpH=(1.6 ... 3.4) at excess of Aluminium(III). Only the complex AlL 2+ was formed with β11=7.6. The results of equilibrium and kinetic measurements indicate that only the species Al3+, AlOH2+ and the neutral form of the ligand contribute to the reaction. Reaction values and rate constants are given. A general acid base catalysis was detected. |
