Definitions
- the carbonaceous pitch used in the present invention is not specially limited, but a petroleum pitch or a coal pitch is preferred.
- organic solvents each having a solubility parameter of 9.2 to 11.0 there are mentioned carbon disulfide (10.0), chloroform (9.3), dichloromethane (9.7), 1,1,2-trichloroethane (9.6), acetone (10.0), methyl ethyl ketone (9.3), pyridine (10.6), dichlorobenzene (10.0), chlorobenzene (9.5), benzene (9.2), naphthalene (10.6) and nitrobenzene (10.2).
- a spinning pitch to be used in the invention which pitch has an optically anisotropic phase content in the range of 5-40 vol.%, preferably 5-35 vol.% more preferably 10-30 vol.%.
- the pitch fiber thus obtained was heated up to 300°C at a rate of 2°C/min in oxygen containing 2 vol.% of NO2 and held at this temperature for 2 minutes, then heated up to 650°C at a rate of 10°C/min in nitrogen and held at this temperature for 30 minutes, and then heated up to 2,500°C at a rate of 100°C/min in nitrogen to afford carbon fiber.
- the optically anisotropic pitch having a mesophase content of 50 vol.% used in Example 2 was pulverized, then subjected to an extraction treatment at 60°C using a mixed solvent (solubility parameter: 7.9) of hexane (50 vol.%) and benzene (50 vol.%) at a rate of 100 ml for 3 grams of the pitch, and insolubles in the mixed hexane-benzene solvent were collected.
- a mixed solvent solubility parameter: 7.9
