本工作通过对γ射线辐解TBP的气相产物分析,得到了体系吸收剂量外推接近零时各气相产物的G值,解释了DBP+MBP酸性产物和气相产物求物料平衡时的差数。还研究了DPSO-TBP体系能量转移动力学,从烃类产物谱中求得的动力学参数与测定酸性产物(DBP+MBP)求得的一致。在此基础上进一步探讨了氢气形成途径:一种可能来源于刺迹(spur)反应,而另一种则为抽氢反应。
In this work, the gas phase products of γ-ray radiolysis of TBP were analyzed. The G value extrapolated near zero was obtained, and the difference between DBP + MBP acid product and gas phase product was calculated. The energy transfer kinetics of the DPSO-TBP system was also studied. The kinetic parameters obtained from the hydrocarbon product spectrum were in agreement with those obtained from the acid product determination (DBP + MBP). On this basis, further discussion of hydrogen formation pathway: one may be derived from the spir (spur) reaction, while the other is the hydrogen abstraction reaction.
