摘　　要：本文合成了Ｎｉ（Ⅱ）的一个配合物Ｎｉ（Ｎｉｃａ）２Ｃｌ２（Ｎｉｃａ表示尼克酰胺）。用元素分析、红外光谱、热重及量热分解对该配合物进行了表征，并对其热分解过程进行了研究，运用Ａｃｈａｒ法和ＣｏａｔｓＲｅｄｆｅｒｎ法，推断出该配合物第一步热分解的非等温动力学方程为：ｄα／ｄｔ＝Ａｅ－Ｅ／ＲＴ３／２（１＋α）２／３［（１＋α）１／３－１］－１。The complex Ni(Nica) 2Cl 2(Nica=Nicotinamid) was prepared.Its structure was assigned on the basis of element analysis, IR,TG and DSC.Its kinetics of thermal decomposition was studied under non isothermal condition. The possible equation of non isothermal kinetics at first step was suggested by the Achar method and the Coats Redfern method. The kinetic equation may be expressed by da/ d t=A e -E/RT 3/2(1+a) 2/3 [(1+a) 1/3 -1] -1 。
