Abstract

Unider the condition that each of the corresponding peaks in DTA and DSC curves are completely separated, the ΔH of each stage of dehydration process of LaCl3.7H2O, PrCl3.6H2O, NdCl3.6H2O SmCl3.6H2O have been determined more accurately. Some peaks are separated for the first time and some data given have not yet been reported in literature.

Key words: DETERMINATION, THERMAL ANALYSIS, HYDRATE, DIFFERENTIAL SCANNING CALORIMETRY, LANTHANUM, DEHYDRATION REACTION, SAMARIUM, PRASEODYMIUM, BETA DIKETONES
