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).
