Title:

METHOD FOR REFINING FULLERENE

Document Type and Number:

Japanese Patent JPH0826710

Kind Code:

A

Abstract:

PURPOSE: To produce high purity fullerene in large quantities at a low cost by simple chromatographic operation from soot or other starting material contg. Fullerene.

CONSTITUTION: When crude fullerene is refined by chromatography for separating a component in large quantities, activated carbon coated silica or activated carbon is used as a filler in a column and the volume ratio of the filler to the crude fullerene is set in accordance with the adsorption capacity of the filler.
