摘　　要：用红外光谱和X 射线分析对双水杨基乙二胺合铬配合物 [Cr(salen) (H2 O) 2 ]NO3进行了表征 ,并用TG和DTG方法对其分解的机理进行了研究 ;通过用微分和积分的方法对其非等温动力学的分析与动力学参数的比较 。A complex of N,N' ethylenebis(salicylideneiminato)diaquochromium(III) nitrate, [Cr(salen) (H 2O) 2]NO 3 was characterized and its decomposition mechanism was studied by TG and DTG. The IR spectrum and X ray analysis were examined for the complex. The non isothermal kinetics data were analyzed by means of the differential and integral methods. The most probable kinetic model function was suggested by comparison of the kinetic parameters.
