Abstract

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.
