More Information
Summary:The invention relates to a preparation method for a stable isotope reagent sodium borodeuteride. The method comprises the following steps: (1) pre-treating a boron-containing substance and quartz sand for complete dehydration, loading the boron-containing substance and the quartz sand in a sealed reaction kettle, adding a pretreated active metal from which a surface oxide layer is removed, connecting a deuterium bag to the sealed reaction kettle, performing heating and stirring, and sucking deuterium for reaction until the volume of the deuterium bag is kept unchanged; (2) after reaction is ended, performing cooling to obtain a sodium borodeuteride product. Compared with the prior art, the preparation method has the advantages that a preparation process route is simple, a preparation condition is mild, less waste gas, wastewater and industrial residues are generated by reaction, and moreover, the prepared sodium borodeuteride has purity capable of reaching 99 percent or above, abundance of 99.9atom% or above
