Kinetic Stability of Tm(III) and Sm(III) Octaphenyltetraazaporphyrin Complexes in Acetic Acid-Based Solvents

摘要

The state of (octaphenyltetraazaporphyrinato)(acetylacetonato)thulium(III) and (octaphenyltetra-azaporphyrinato)(acetylacetonato)samarium(III) in AcOH and in systems AcOH-benzene and AcOH-H_2SO_4 was studied.The stability constant of the acid form of the thulium complex was estimated.The solvoprotolytic dissociation of the complexes in the AcOH-H_2SO_4 and AcOH-benzene systems was studied.
