ABSTRACT:
A method of producing a precursor pitch suitable for the production of carbon fibers, which method includes dissolving a coal tar pitch in a particular solvent to remove a solvent insoluble matter, distilling off the solvent to obtain a purified pitch containing no free carbon, and heat-treating the purified pitch to obtain an objective precursor pitch.
