Abstract:

The 2-carboxybenzaldehyde-1H-benzotriazol-1-aceylhydrazone (C16H13N5O3) has been synthesized and used in preparing thirteen novel rare earth complexes. The complexes were characterized by elemental analysis, FT-IR, and UV-Vis, and the formula is RE (C16H11N5O3)·NO3·xH2O·yC2H5OH (RE=La, Ce, Pr, Nd, Sm, Eu, Tb, Ho, Er, Yb) and RE(C16H12N5O3)2·NO3·5H2O (RE=Gd, Dy, Y) .The thermal decomposition processes of the thirteen complexes were studied by thermal gravimetric technology and their apparent activation energy values were calculated by Kissingers and Ozawass method.
