| Abstract: | An integrated technology for manufacture of fullerenes was developed. It includes the following stages: synthesis of a fullerene black, extraction of a mixture of fullerenes from the black, preliminary separation of the mixture into concentrates enriched in C60 and C70 fullerenes, and production of C60 and C70 fullerenes of purity exceeding 99.5 and 98.0 wt %, respectively, from the concentrates. |
