邻香兰素-D,L-苏氨酸过渡金属配合物的合成、表征及热稳定性研究

Synthesis,Characterization and Thermodynamic Stability of Transitional Metal Complexes of (o-vanillylidene)-D,L-Threomine

采用分步合成法合成了以邻香兰素 - D,L-苏氨酸席夫碱为配体的铜、锌、钴、镍配合物 ,并进行了元素分析和红外光谱表征 .同时 ,利用差热分析对配合物的热稳定性进行了研究 ,得出其热稳定性次序为 :钴配合物 >锌配合物 >镍配合物 >铜配合物 .

In this paper, a new schiff base derived from o -vanillin and D,L-threomine and their Cu(II), Zn(II), Co(II) and Ni(II) complexes are synthesized. The complexes are characterized by element analysis and infrared spectra. The thermodynamic stability are obtained from the analysis of the TG-DTA, and the sequence is Co(II) complexes>Zn(II) complexes>Ni(II) complexes>Cu(II) complexes.
