    • Provided are a process for removing an alkali metal from a sooty residue by a easy and safe method and a process for production and purification in high purity by preliminarily enhancing the content rate of alkali metal doped fullerenes utilizing a certain organic solvent as the separator. The alkali metal that doesn't react with fullerenes and compounds thereof are removed by immersing the sooty residue prepared by the plasma method or the arc discharge method in aqueous solvent and stirring it (S100), and are collected as residue. The residue is immersed in a separator, for example, toluene (S101) and stirring is carried out (S102). Then, centrifugal separation and the like are carried out to separate the solution and the residue (S103). The content rate of the alkali metal doped fullerenes in the residue are preliminarily enhanced by repeatedly carrying out the steps S101 to S103 for the residue. The alkali metal doped fullerenes can be purified in high purity and produced without complicated operations by applying liquid chromatography to the residue in which the content rate of the alkali metal doped fullerenes is enhanced (S107).
    • 本发明提供了一种通过简单且安全的方法除去碱金属的方法,以及通过使用某种有机溶剂作为隔膜预先提高掺杂了碱金属的富勒烯的含量,从而高纯度地生产和纯化的方法。 通过将通过等离子体法或电弧放电法制备的煤烟渣浸入水性溶剂中并搅拌,除去不与富勒烯及其化合物反应的碱金属(S100),作为残渣收集。 将残余物浸入分离器中,例如甲苯(S101),并进行搅拌(S102)。 然后,进行离心分离等分离溶液和残渣(S103)。 残留物中的碱金属掺杂的富勒烯的含有率通过反复进行残留物的步骤S101〜S103而被预先提高。 碱金属掺杂的富勒烯可以以高纯度纯化并且通过向其中增加碱金属掺杂的富勒烯的含量比例增加的残余物进行液相色谱法而无需复杂的操作(S107)。
