摘要
在苯甲醚—三氟化硼体系中采用化学交换法,进行硼同位素分离生产性实验,可使^(10)B在液相富集,^(11)B在气相中富集。在此基础上,进行硼同位素分离试生产。获得交换塔和络合塔正常运行参数,开发在分解塔内将络合物成功分解的工艺技术,验证在交换塔内采用聚四氟乙烯丝网填料富集硼同位素可行性,探讨操作压力、流量等工艺参数对^(10)B富集的影响,为实现硼同位素分离工业化的正式投建提供依据。
The boron isotopes separation test was performed by chemical exchange reaction in the benzene ether - three boron fluoride system, which resulted to the boron isotopic enrichment of -10 in the liquid phase, the boron isotopic enrichment of -11 in the gas phase. After then, boron isotope separation trial production has been finished. In this process, the exchange column and complex tower normal operating parameters and the complex tower technology have been obtained, the problems of material distillation purification is solved, boron isotopes feasibility with PTFE packing enrichment is verified in an exchange column. Also, effect of operating pressure, flow and other parameters on boron -10 isotopic enrichment experiments and the effect and properties of the PTFE packing have been investigated in the existing system. All the results are very useful for the industrialization of the boron isotopes separation system.
