~(60)CO辐照磷酸三丁酯形成三聚酸性磷酸酯的研究

INVESTIGATION ON THE FORMATION OF TRIMER OF DIBUTYL ACID PHOSPHATE AND TRIBUTYL PHOSPHATE IN 60Co-IRRADIATED TBP SYSTEM

摘要: 用萃取和柱色层方法从γ辐照过的TBP中分离出了一种酸性强络合辐解产物,用TLC和GC方法鉴定了未知物的纯度;并通过元素分析、IR、MS、电位滴定等方法确定该未知物为两个TBP分子与一个DBP分子的三聚体,即TBP·TBP·DBP。本工作还就该聚合物的萃取行为,水溶性及其生成G值与TBP吸收剂量的关系做了探讨。

Abstract: In this work, a main unknown radiolysis product with high complexing capacity is separated and purified by means of extraction and column chrornatography. The purity of the product is identified by TLC. The structure and some chemical behaviors of this product are investigated.The results of IR and MS and other classical chemical analyses show that the product is a trimer containing a skeleton of two TBP molecules and one DBP molecule i. e. TBP·TBP·DBP.
