LIQUID-CHROMATOGRAPHIC SEPARATION OF GEOMETRICAL ISOMERS USING SPHERICAL CARBON PACKINGS PREPARED FROM SPHERICAL CELLULOSE PARTICLES

The packings of spherical carbon beads were prepared by graphitizing t he spherical cellulose particles. A types of carbon spherical packings were obtained by various degrees of graphitization. These packings we re characterized by examining their chromatographic properties. The hi gher the degree of graphitization is, the higher the pi-electron recog nition became, although there was no change in the selection for a met hylene group. The mechanism for recognizing the pi-electron and the st eric selectivity is described and discussed.
