摘要： 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).

摘要： In order to isolate and purify an endohedral fullerene, a solvent washing was performed using toluene to concentrate the endohedral fullerene in a residual, but endohedral fullerene could not be efficiently purified because impurities other than the endohedral fullerene could not be sufficiently removed. Thus, the endohedral fullerene is isolated and purified by using a solvent such as chloronaphthalene or tetralin having a high solubility for the endohedral fullerene and concentrating the endohedral fullerene in the solvent. The endohedral fullerene isolated and purified by solvent extraction has a cluster structure where the endohedral fullerene is surrounded with empty fullerenes. Thus, this endohedral fullerene is highly stable and is a useful material applicable to various fields such as medical care and electronics.
