摘　　要：合成并表征了水杨醛 1H 苯并三唑乙酰腙(C15H13N5O2,简称SBTH)及其与稀土的新配合物RE(HL)2ClO4(RE=Pr,Nd;HL=C15H12N5O2),通过TG DTG、DSC研究了配合物的热分解过程,得到了各配合物的分解焓,并利用Kissinger法及Ozawa法计算出各配合物分解的表观活化能.在DMF(N,N 二甲基甲酰胺)中测量了配合物不同浓度时的溶解热,得到了它们的标准摩尔溶解焓.通过恒容燃烧能的测定计算出配合物的标准生成焓.Two new rare earth complexes RE (HL)_(2 )ClO_(4)(RE=Pr, Nd; HL=C_(15)H_(12)N_(5)O_(2 )) of Salicylaldehyde-1H-benzotriazol acetyl hydrazone (C_(15)H_(13)N_(5)O_(2), SBTH) and Lanthanide perchlorates have been synthesized and characterized. The TG-DTG, DSC were carried out to study the thermodecomposition process of the complexes and the enthalpies of decomposition were obtained. The apparent activation energies were calculated by the Kissinger's method and Ozawa's method. The enthalpies of solution in DMF for the complexes were measured. The standard enthalpy of formation was obtained by the determination of the combustion energy.
