Abstract:

At present a big part of fullerenes are produced from high pure graphite electrode, and the products are mixtures of C₆₀, C₇₀ etc. Because they are of very similar structure, their physical and chemical properties are very similar,so the separation of the mixture is one of the most interesting subjects. Recently,HPLC is generally applied to do this work, and this method is now still in the phase of research and development. Based on the work of other people and on thermodynamic theory of chromatography, a quantitative relationship model between the separation factor and carbon number of fullerenes in HPLC is proposed in this paper,and verified successfully by different author's experimental data in different papers.
