用硝酸钕与苯甲酰甘氨酸(C9H9NO3)和吡啶(C5H5N)在95%乙醇中反应,合成了一种新型稀土三元配合物,通过元素分析和化学分析确定其组成为Nd(C9H8NO3)3(C5H5N).4H2O,并通过红外光谱、紫外光谱对配合物的结构进行了表征.根据TG-DTG曲线研究了配合物的热分解过程;利用Satava-Sestak积分法和Achar-Brindley-Wendworth微分法对脱水阶段的非等温动力学数据进行分析,推断出脱水阶段动力学方程为dα/dt=A/[β.e-E/RT(1-α)].研究了配合物的抑菌活性,抑菌活性试验结果表明,标题配合物对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌具有不同程度的抑菌作用,而对苏云金芽孢杆菌无抑制作用.
A novel rare earth ternary complex was synthesized by the reaction of neodymium nitrate with benzoylglycine (C9H9NO3) and pyridine (C5H5N) in 95% ethanol. Its composition was determined by elemental analysis and chemical analysis to be Nd (C9H8NO3) 3 C5H5N) .4H2O. The structure of the complex was characterized by FT-IR and UV. The thermal decomposition of the complex was studied by TG-DTG curve. The thermal decomposition of the complex was studied by Satava-Sestak integration and Achar-Brindley-Wendworth differential The kinetic equation of dehydration was deduced as follows: dα / dt = A / [βeE / RT (1-α)]. The antibacterial activity, antibacterial activity The experimental results show that the title complex has different degree of bacteriostatic effect on Escherichia coli, Staphylococcus aureus and Bacillus subtilis, but has no inhibitory effect on Bacillus thuringiensis.
