摘要
合成的标题化合物晶体—C_(26)H_(26)N_4O_5Zn属正交晶系,空间群P2_12_12_1,a=0.9460(4)nm,b=1.4114(4)nm,c=1.9254(4)nm,Z=4.利用热重分析对配合物第二步热分解过程进行了非等温动力学研究,探讨了反应的可能机理,得到其相应的动力学参数,非等温动力学方程为:da/dt=A·e^(-E/RT)·2(1-α)^(3/2)
The crystal of o - vanillin - serine dipyridine Zn( II ) C26H26N4O5Zn was synthesized and its structure was determined by single crystal X - ray diffraction method. The complex is orthorhombic system, space group P212121 with a =0.9460(4)nm,b = 1.4114(4)nm,c = 1.9254(4)nm, V = 2. 571(2)nm3, Z = 4. The kinetics of thermal decomposition reaction of the complex was studied under a non - isothermal condition by TG. The kinetic parameters were obtained from the analysis of TG,DTG curves by integral and differential methods. The kinetic equation of thermal decomposition reaction is:da/dt=A·e -E/RT·(1-a)2
