摘　　要：将金属原子或离子置于以Ｃ６０、Ｃ８２为代表的富勒烯笼内形成金属富勒烯包合物是目前富勒烯研究的热点课题［１～３］．合成的金属富勒烯常伴随生成较难分离的空心富勒烯，传统的索氏提取法效率又较低，使得金属富勒烯的深入研究受到限制［１，２］．本文采用改进的高温...The traditional Soxhlet extraction of lanthanofullerenes was improved and the high temperature and high pressure method with different extraction solvents was used. Its found that La@C 2 n can be efficiently extracted with toluene and pyridine from the insoluble part of the soot after the toluene Soxhlet extraction. Pyridine can more efficiently and selectively extract lanthofullerenes, especially La@C 82 , while toluene can extract La@C 74 , which is a new member added to the soluble species to lanthanofullerenes.
