  Extraction of actinides by Tri-n-butyl phosphate derivatives: Effect of substituents

  摘要：

  Tri-n-butyl phosphate (TBP) is most extensively used extractant in the nuclear fuel cycle. The present work investigates the effect of substituents and their role in the basicity of organophosphorus extractant on the uptake of actinides. In this connection, we have synthesized six different analogues of TBP by altering one of its butoxy group. The synthesized TBP derivatives were well characterized and evaluated for their solvent extraction behavior towards U(VI), Th(IV), Pu(IV) and Am(III), as well as acid uptake as a function of nitric acid ranging from 0.01 to 6 M and the data provides the comparison of their extraction behavior with that of 30% (1.1 M) tri-n-butyl phosphate under identical conditions. It was observed that distribution coefficient values strongly depend on the nature and size of the substituents. The presence of electron donating groups enhances the uptake of the actinides and the distribution coefficient values were significantly larger as compared to that of TBP. In addition, the effect of sodium nitrate on the extraction of uranium and enthalpy of extraction were also studied and revealed that the extraction process was exothermic. (C) 2017 Elsevier B.V.

  The present invention provides a lubricating oil composition for refrigerating machine capable of enhancing the anti-wear property of the entire system when used together with 1,1,1,2-tetrafluoroethane (HFC-134a) which does not act as an extreme-pressure agent. This composition exhibits an anti-wear property superior to that of the existing lubricating oil composition for refrigerating machine using CFC-12. The ester expressed in any one of Formulae (I), (V), (VI) is used as the base oil or as an additive to the base oil. (The symbols in the formulae are as specified in Specification herein.)

  本发明提供了一种用于制冷机的润滑油组合物，该组合物与不作为极压剂的 1,1,1,2- 四氟乙烷（HFC-134a）一起使用时，能够提高整个系统的抗磨损性能。 这种组合物的抗磨损性能优于使用 CFC-12 的现有制冷机润滑油组合物。 式（I）、（V）、（VI）中任一式所表示的酯可用作基础油或基础油的添加剂（式中符号如本说明书所述）。
