| titleOfInvention | The separation method of embedded fullerene and empty fullerene |
| abstract | The present invention relates to the separation methods of a kind of embedded fullerene and empty fullerene; it is reacted the following steps are included: lewis acid is added into the organic solution containing empty fullerene and embedded fullerene; embedded fullerene generates precipitating after reacting with lewis acid; wherein; reaction carries out under protective atmosphere, and reaction temperature is room temperature；Precipitating is separated from reaction solution, empty fullerene stays in reaction solution；Then the aqueous solution of the chelating agents such as EDTA, DTPA, EGTA, EDTP is added in the precipitating gone out using organic solvent separated and dissolved, stratification after mixing forms organic phase and water phase, separates organic phase and water phase, contains embedded fullerene in organic phase.The present invention substantially reduces the disengaging time of embedded fullerene, improves itself and lewis acidic solution complexation efficiency. |
