Abstract

The solubilities of the ternary Y(ClO4)3.3H2O-18-crown-6-MeCN system at 20?have been investigated by the modified semimicro method for study of phase equilibrium Two kinds of complexes are formed at 20? namely Y(ClO4)3.18-crown-6.3H2O.2.5MeCN and Y(ClO4)3.2(18-crown-6).3H2O.2MeCN, which were isolated, and dried to give Y(ClO4)8.18-crown-6.3H2O and Y(ClO4)3.2(18-crown-6).3H2O, resp. The composition and properties of the 2 complexes have been investigated by IR spectra, conductivity measurements, DTG, TG and DSC. The enthalpies of dehydration and decompns. have been determine for these two complexes by DSC.
