Abstract: The solubilities of ternary system, PrCl3·3H2O-18C6-C2H5OH, at 25℃ were investigated by a semimicro method for the study of phase equilibrium and the refractive indexes of saturated solutions were determined. Three kinds of stoichiometrical coordination compounds can be formed in the system, their chemical compositions are 2PrCl3·18C6·6H2O·C2H5OH, 4PrCl3·3(18C6)·12H2O and PrCl3·18C6·3H2O. The three kinds of coordination compounds were prepared on the basis of the result of phase equilibrium, and characterized by IR spectra, conductivity measurements, TG, DTG and DSC.
