摘　　要：报导１，４－双（１′－苯基－３′－甲基－５′－氧代吡唑－４′－基）丁二酮双缩甘氨酸合双铜（Ⅱ）配合物的合成及热分解反应动力学．运用Ａｃｈａｒ法与Ｃｏａｔｓ－Ｒｅｄｆｅｒｎ法对非等温动力学数据进行分析，求得配合物非等温热分解反应的活化能Ｅ＝１６５．１３ＫＪ·ｍｏｌ－１，其动力学方程为ｄα／ｄｔ＝３／２Ａｅ－Ｅ／ＲＴ（１－α）４／３［１／（１－α）１／３－１］－１．动力学补偿效应表达式为ｌｎＡ＝－０．２６９８Ｅ＋０．１９４２．The paper reports the synthetic procedure and character of copper(Ⅱ) binuclear coordination compound of schiff base derived from 1,4 bis (1′ phenyl 3′ methyl 5′pyrazolone 4′)butanedione and glycine.The non isothermal kinetics of thermal decomposition of the complex has been studied from the TG-DTG Curves by means of the Achar and Coats Redfern methods,the most probable kinetic equation can be expressed as d α/ d t=3/2Ae -E/RT (1-α) 4/3 [1/(1-α) 1/3 -1] -1 . The mathematics expression of the kinetic compensation effect is found to be ln A=0.2698E+0.1942.
