摘要: 报导了磷酸三丁酯(TBP)对环己烷辐解的抑制效应。通过观察TBP对环己烷主要辐解产物氢气、环己烯、二环己烷的产额的影响和结合TBP-环己烷二元体系激发单重态敏化实验的结果。发现: TBP对环己烷辐解的抑制可分为两个过程, a)激发能传递, b)电子捕获。求得环己烷偕离子对产额为3.8, TBP捕获电子的反应系数为6.3 L·mol~(-1)。

Abstract: The inhibition effects of tributylphosphate on the radiolysis of cyclohexane have been reported. Combintion of the inhibition effects of the radiolytical productshydrogen gas, cyclohexene, bicyclohexyl with results of excitation energy transfer, it was found that the inhibition effects of TBP are performed by two processes: a)excitation energy transfer, b) electron capture. We obtained that the yield of the geminate ion pairs of cyclohexane is 3.8, and the electron capture coefficient of TBP is 6.3 L·mol~(-1).
