【摘要】 合成的标题化合物晶体(C23H29N3O6Zn)属正交晶系,空间群P212121,晶胞参数a=0.9345(2),b=2.6620(5),c=0.9748(4)nm,V=2.425(2)nm3,Z=4利用热重分析对配合物第一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·(1—a)
【Abstract】 The complex[Zn(L)(C5H5N)2]·2H2O(L = 3 - methoxysalicylidene - L -valine)was synthesized The complex crystalizes in an orthorhombic system, space group is P212121, cell parameters:a = 0.9345(2),b = 2.6620(5),c = 0.9748(4)nm, V = 2.425(2)nm3,Mr = 508.87, Z=4, with R = 0. 074, Rw= 0. 076. 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)
