摘要：

Association of tris(pentane-2,4-dionato)cobalt(III) [Co(acac)3] with chlorophenols, dichlorophenols, trichlorophenols and pentachlorophenol in heptane has been studied by the liquid-liquid partition technique in the heptane-0.10 mol dm-3 aqueous perchlorate solution system. From the partition equilibrium, the association complexes with the chlorinated phenols(HA) were found to be Co(acac)3.HA and Co(acac)3.2HA, and the association constants were determined. Existence of the hydrogen bond between the hydroxyl proton of the phenols and Co(acac)3 was evidenced from the H-1 NMR measurement. The relationship between the association constant and the acid-dissociation constant of the phenols is discussed.
