摘　　要：锂在核能、电子、宇航、医学、化工等产业都受到广泛应用,因此锂同位素的分离具有重要意义。本文将苯并-15-冠醚-5与6-溴己酸在催化剂多聚磷酸的催化下反应获得离子液接枝冠醚,最终将合成的离子液接枝冠醚结合到特定石墨烯基体上作为萃取材料,从而用于分离锂同位素。Lithium is widely used in nuclear energy,electronics,aerospace,medicine and chemical industry,so the separation of lithium isotopes is of great significance.Benzo-15-crown-5 ether was reacted with 6-bromocaproic acid under the catalysis of catalyst polyphosphate to obtain ionic liquid grafted crown ether.Finally,the synthesized ionic liquid grafted crown ether was combined with specific graphene film matrix as extraction material,which was used to separate lithium isotopes.
