| 摘 要： | 综述了化学交换精馏法分离同位素硼-10的技术进展。在介绍化学交换精馏法分离同位素硼-10原理的基础上，分析了目前工业化过程分离同位素硼-10存在的问题，指出新的络合剂-硝基甲烷(CH3NO2)、丙酮(Acetone)、甲基异丁基酮(MIBK)、二异丁基酮(DIBK)等用于从三氟化硼分离硼-10具有更高的分离系数，形成的络合物具有更好的稳定性，其中CH3NO2是现有同位素硼-10分离工艺过程较为理想的替代络合剂。

| Abstract: | Advances in boron10 isotope separation by chemical exchange distillation are reviewed. On the basis of introducing the principles of separating boron10 isotope by chemical exchange distillation, the problem in largescale boron10 production is discussed. Several new donors, including nitromethane, acetone, methyl isobutyl ketone (MIBK) and diisobutyl ketone (DIBK), which have a larger separation factor if used in separation are introduced. The com plexes between these new donors and boron trifluoride (BF 3) are more stable than the donors examined before. Among these new donors nitromethane could be a promising substitute for the donor in present use to develop new technology of separating boron10. |
