摘要：
TTA, a classical complexing agent of metallic cations, has been studied by UV-vis in the ionic liquid (IL) 1-methyl-3-butylimidazolium bistriflimide (Bumim Tf2N), in the presence of variable amounts of water. Depending on the water content, the ketohydrate/enol equilibrium kinetics can last up to tens of hours. Modelling by use of classical homogeneous kinetic equations appears unsatisfactory, which pledges for the existence of non-homogeneous phenomena in such solutions, most probably related to the state of water in ILs.
