摘　　要：采用二硫化碳重结晶富勒烯混合物或二硫化碳二次抽提烟灰以提取高富勒烯（ｈｉｇｈｅｒｆｕｌｅｒｅｎｅｓ，Ｃｎ，ｎ＞７０）。产物经高效液相色谱分析，高富勒烯的含量从１％分别提高到４％和６％；经激光飞行时间质谱证明，产物中除含主要成分Ｃ６０和Ｃ７０以外，还含有Ｃ７６、Ｃ７８、Ｃ８２、Ｃ８４以及更高碳原子的富勒烯。Higher fullerenes may be obtained by CS 2 extraction of soot or by recrystallization of crude fullerenes mixture from CS 2 solution The contents of higher fullerenes were concentrated from about 1% to 4% and 6%by these procedures,respectively The ingredients in product thus obtained were identified by laser mass spectrometry and HPLC
