精馏与化学交换法分离硼同位素中液相络合剂的研究

采用苯甲醚、硝基甲烷、丙酮、甲基异丁基甲酮4种络合剂分别与三氟化硼合成出了4种络合物体系。对这4种络合物体系性能进行了实验研究与分析,为中试及工业化生产高丰度硼10同位素提供设计依据。通过分析认为硝基甲烷和丙酮分离系数较高,在性能上优于目前常用的苯甲醚系统,更适宜于应用在硼同位素的分离生产过程中,但是否在工业生产中更能减少能耗,缩短生产周期,降低成本还需要更进一步详细的工业生产经济分析对照。

Study on the liquid complex of boron isotopes separation by chemical exchange reaction and distillation

Using anisole,nitromethane,acetone,methyl isobutyl ketone as the donors,four complex compounds were prepared.The basic properties of four complex compounds were experimentally researched respectively,which provided the important data for the production of boron isotopes in the pilot and industrialized scale.These(preliminary) studies indicate that the boron fluoride with nitromethane or acetone system with higher separation factor is superior to the anisole system used currently,but a more detailed study is needed for a realistic economic(comparison) of the two processes.
