Purification of C70 Using Charcoal as a Stationary Phase in a Flash Chromatography Column.

Abstract

Described is a method for the purification of C60 and C70 using a flash chromatography column that contains charcoal as the stationary phase. A number of functionalized aromatic solvents are studied and their efficacy for extraction, NMR spectral acquisition, and chromatographic purification of fullerenes is discussed. Ortho-dichlorobenzene was chosen as the best solvent for these applications and examples of its use in the extraction of higher fullerenes (>C84) and in the rapid acquisition of (13)C NMR spectra are given. Finally, single column purification of both C60 and C70 is discussed. Starting with a typical arc-derived mixture of soluble fullerenes, 5.97 g of C60 at >99.9% purity and 1.58 g of C70 at >97% purity were produced in a single column pass. jg p.3
