THERMAL DECOMPOSITION KINETICS OF OXAMIDE COMPLEXES(Ⅰ)-N,N′-BIS-(2-AMINOETHYL)OXAMIDOCOPPER(Ⅱ)

采用TG -DTG -DTA热分析技术研究了N ,N′ -双 (2 -氨乙基 )草酰胺合铜 (II)配合物在空气气氛中的热行为 ,用微分法 (Achar法 )和积分法 (Coats_Redfen法 )协同处理非等温TG数据 ,通过对比热分解动力学参数E和lnA ,提出了N ,N′ -双 (2 -氨乙基 )草酰胺合铜 (Ⅱ )配合物热分解反应机理 。

The thermal decomposition of N,N′_bis(2_aminoethyl)oxamidocopper(Ⅱ) complex under dynamic air atmosphere was studied by TG, DTG and DTA technique. The non_isothermal kinetics data were analyzed by means of the Achar method and the Coats_Redfen method. The most probable kinetic model function was suggested by comparison of the kinetic parameters. The mathematical expressions of E and ln A were derived from the kinetic compensation effects.
