Preparation method of perdeuterated benzene

The invention relates to a preparation method of perdeuterated benzene, and belongs to the field of organic chemical synthesis. According to the method, cheap deuterium water is used as a deuterium source, so that the use of an expensive deuterium source is avoided; hexabromo-benzene is used as a raw material, so that the technology of efficiently utilizing isotopes is realized; a non-deuterated organic solvent is used as a solvent, so that the use of an expensive deuterated reagent is avoided; cheap metal is used as a catalyst, and expensive metal is prevented from being used. The method is cheap, efficient, pollution-free and suitable for industrial production. The deuterated benzene can be used in the fields of organic photoelectricity, medicines, pesticides and the like. 本发明涉一种全氘代苯的制备方法，属于有机化学合成领域。所述方法以廉价的氘水为氘源，避免了昂贵氘源的使用；以六溴苯为原料，实现了高效利用同位素的技术；以非氘代有机溶剂为溶剂，避免使用昂贵氘代试剂；使用廉价金属作为催化剂，避免使用昂贵金属。该方法廉价、高效、无污染，适用于工业化生产。氘代苯可用于有机光电、医药农药等领域。
