Abstract
The packings of spherical carbon beads were prepared by graphitizing the spherical cellulose particles. A types of carbon spherical packings were obtained by various degrees of graphitization. These packings were characterized by examining their chromatographic properties. The higher the degree of graphitization is, the higher the π-electron recognition became, although there was no change in the selection for a methylene group. The mechanism for recognizing the π-electron and the steric selectivity is described and discussed.
