| titleOfInvention | Separators for Alkali Metal Doped Fullerenes, Method for Separating Alkali Metals and Compounds Thereof from Fullerenes, Processes for Purification and Production of Alkali Metal Doped Fullerenes, and System Therefor |
| abstract | 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 (S 100 ), and are collected as residue. The residue is immersed in a separator, for example, toluene (S 101 ) and stirring is carried out (S 102 ). Then, centrifugal separation and the like are carried out to separate the solution and the residue (S 103 ). The content rate of the alkali metal doped fullerenes in the residue are preliminarily enhanced by repeatedly carrying out the steps S 101 to S 103 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 (S 107 ). |
