对由水杨醛及其衍生物所形成的Schiff碱配合物的研究已有不少报道,其中一些配合物具有抑菌、抗癌和抗病毒活性,可作为生物氧载体的模型化合物.我们曾合成一系列水杨醛衍生的Schiff碱与过渡金属离子的配合物.为进一步考察这类配合物的合成、结构,性能和应用及其相互关系,本文在合成N-水杨醛甘氨酸三吡啶合镍(Ⅱ)的基础上,采用TG、DTG和DTA技术研究了该配合物的热分解过程。并借助TG和DTG曲线,采用微分法中的Achar法和积分法中的Coats-Redfern法,通过比较各种不同机理函数时的动力学参数,
There are many reports on the Schiff base complexes formed from salicylaldehyde and its derivatives, some of which have antibacterial, anticancer and antiviral activities and are useful as model compounds for bio-oxygen carriers. Synthesis of a series of salicylaldehyde-derived Schiff base complexes with transition metal ions.In order to further investigate the synthesis, structure, properties and applications of these complexes and their interrelationship, this paper synthesizes N-salicylaldehyde glycine tripyridines On the basis of nickel (Ⅱ), the thermal decomposition process of the complex was studied by TG, DTG and DTA techniques. By means of the TG and DTG curves, the Achar method in differential method and the Coats-Redfern method in integral method are used to compare the kinetic parameters of different mechanism functions,
