| Abstract: | Extraction of fullerenes from carbon soot by trichloroethylene has been studied. We have found that C60 forms a solvate with trichloroethylene (C60 · C2HCl3:a=31.31(1);b= 10.156(4);c=10.146(4) Å;V=3228.6 Å3,Z=4,d
calc=1.752 g cm–3, orthorhombic symmetry). Its thermal stability has been studied using TG and DSC. A phase transition of the first order at 167 K has been detected.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 7, pp. 1248–1250, July, 1994.The authors are grateful to V. P. Bubnov and I. S. Krainskii for providing them with the samples of fulle-rene-containing carbon soot, and to M. G. Kaplunov and A. V. Zvarykina for assistance in the work.This work was carried out with the financial support of the Russian Foundation for Basic Research, Project Nos. 93-03-18705 and 93-03-5650. |
