以6-羟基-2-吡啶羧酸为原料,经5步反应合成得到一种新型四齿β-二酮1,2-羟基吡啶酮衍生物。通过红外、核磁、质谱对其结构进行了表征。采用电位-光谱结合的方法,测定了四齿β-二酮1,2-羟基吡啶酮衍生物与UO2+2、Cu~(2+)、Zn~(2+)和Fe~(3+)的络合能力。结果表明,四齿β-二酮1,2-羟基吡啶酮衍生物对UO2+2和Fe3+有明显的络合能力,有望成为一种新型铀酰离子促排剂(p UO2=15.4)和铁螯合剂(p Fe=21.22)。
A new type of tetradentate β-diketone 1,2-hydroxypyridone was synthesized by 5 steps using 6-hydroxy-2-pyridinecarboxylic acid as raw material. Its structure was characterized by IR, NMR and MS. Potentiometric - spectrophotometric method was used to determine the interaction between tetradentate β - diketone derivatives and UO2 +2, Cu2 +, Zn2 + and Fe3 + Complexity. The results showed that the tetradentate β-diketone derivative has obvious complexation ability with UO2 + 2 and Fe3 +, and is expected to be a new uranyl ion promoter (p UO2 = 15.4) and iron Chelator (p Fe = 21.22).
