Abstract

Abstract: The rare earth complexes with m-nitrobenzoic acid (LnL₃·nH₂O, n=2,Ln=La-Lu and Y; n=0, Ln=Sc. HL=m-nitrobenzoic acid) were synthesized and characterized by elemental analysis and IR spectra. The mechanism of thermal decomposition of complexes were studied by means of TG-DTA and high temperature X-ray diffractometry. The activation energies and enthalpy changes of dehydration process of LnL₃·2H₂O were calculated. The phase change process of the complexes has been studied by DSC. The ultrafinity of the products of decomposition was observed.

Key words: m-nitrobenzioc acid, rare earth complex, thermal decomposition, phase change
