For the purification of Be²⁺-, Al³⁺-, Sc³⁺-, V³⁺-, VO²⁺-, Cr³⁺-, Mn³⁺-, Fe³⁺-, Co³⁺-, Co²⁺-, Ni²⁺-, Zn²⁺-, Zr⁴⁺- and In³⁺-trifluoroacetylacetonates, a new sublimation method was investigated in the flow of helium containing the vapor of trifluoroacetylacetone under atmospheric pressure. An entrainer sublimator equipped with a ligand vapor generator was used. From the results of elemental analysis and the measurements of melting point, it was realized that the proposed method gave satisfactorily purified samples without any associated thermal decomposition.
