| Abstract: | The solid coordination compounds of RECl3·3H2O(RE=Pr, Gd)with 18C6 have been prepared in C2H5OH, their chemical composition is: RECl3·18C6·3H2O. The propertics of the complexes have been investigated by IR, solubility, DTG and TG. The thermal dccomposition processes of the complexes have been proposed. The integral heats of solution of RECl3·18C6·3H2O in C2H5OH, 18C6 in C2H5OH, and the heats of solution and coordination of RECl3·3H2O in 18C6-C2H5OH solution have been measured calorimctrically at 298.15K. By means of a thermochcmical cycle suggested in this paper, the reaction heat of RECl3·3H2O(s)with 18C6(s), forming RECl3·18C6·3H2O(s), and the standard molar enthalpics of formation for the two comnlcxcs were obtained. |
