用硝酸钕与对羟基苯甲酸(HOC6H4COO)和咪唑(C3H4N2,简称Im)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(HOC6H4COO)4(C3H4N2)2.4H2O,并通过红外光谱、紫外光谱对配合物进行了表征.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)[-ln(1-α)-2]/3}.研究了配合物的抑菌活性,抑菌活性试验发现标题配合物对苏云金芽孢杆菌、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效果.
A novel rare earth ternary complex was synthesized by the reaction of neodymium nitrate with p-hydroxybenzoic acid (HOC6H4COO) and imidazole (C3H4N2, abbreviated as Im) in 95% ethanol. Its composition was determined by elemental analysis and chemical analysis as Nd (HOC6H4COO ) 4 (C3H4N2) 2.4H2O were synthesized and characterized by IR and UV spectroscopy. The thermal decomposition of the complex was studied by TG-DTG curve. The Satava-Sestak integral method and the Achar-Brindley-Wendworth differential method Based on the analysis of the non-isothermal kinetic data of the dehydration stage, the kinetic equation of the dehydration stage is deduced as dα / dt = A / β.eE / RT {(1-α) [- ln (1-α) -2] / 3 The antibacterial activity and antibacterial activity of the complex were studied. The title complex showed different antibacterial activity against Bacillus thuringiensis, Escherichia coli, Staphylococcus aureus and Bacillus subtilis.
