Phosphorus(V) oxoacid derivatives as efficient ligands for boron isotope separation by chemical exchange method

A micro-channel distillation device was used for the process intensification method to separate boron isotopes, 10B and 11B. Three-dimensional (3D) printing technology was introduced to manufacture the micro-channel device, which used the chemical exchange method with anisole as the donor to separate the boron isotopes. This device was tested in total reflux mode, and the height of an equivalent theoretical plate of the micro-channel distillation equipment was reduced to 1.56 cm. The accurate control of pressure and temperature, as well as the flow rate of the complex, were factors that affected separation ability. Thus, for process intensification, this micro-channel distillation device can be operated horizontally and connected in series into similar modules to effectively improve separation efficiency and reduce the size of the equipment.

Pyrolysis Reaction

Nowadays in China, excessive import of boron isotope has always been the bottleneck to its industrial applications in nuclear, mechanical, steel and electronic fields. To pull the boron industry out of the mire of import, it is prerequisite to study the enriching and refining of boron isotope. In this work, we present an experimental setup of boron isotope separation by chemical exchange distillation with focus on pyrolysis reaction. After repeated tests, the optimal temperature of pyrolysis reaction (i.e., 140oC) had been found and the best enrichment of 10B (i.e., 34.4%) could be achieved when the reaction continued to the 8th day. These results indicate that the more completely the pyrolysis reaction performs, the better enrichment of 10B arrives.

Isotopes Separation

Abstract The enrichment ratio of 10B in the top and bottom component with the dynamic change of feed fluctuation and periodic wave on the separation process of the boron isotopes separation by chemical exchange method had been studied and a dynamic model was set up. The results indicate that when the feed amount is in the column load limit, the dynamic responses of top and bottom separation plate match well with the condition when feed flow rate is invariable. While when the exchange column is overloaded, the feed flow rate variation influences 10B abundance ratio greatly. With the increasing of the fluctuation period, the longer the wave period, the bigger the amplitude around the average line in top product. However, big increase of feed fluctuation will reduce the 10B abundance ratio of bottom product.
