Method for manufacturing isotropic pitch |
| abstract |
(57) [Abstract] [Purpose] An object of the present invention is to produce an optically isotropic pitch that does not substantially contain an optically anisotropic structure and has improved infusibility. [Structure] 1 to 10% by weight of an aromatic nitro compound is added to heavy coal oil, and the temperature is set to 150 to 400 ° C. ~ 120 minutes treatment to obtain a reformed product, the reformed product is dissolved in a monocyclic aromatic hydrocarbon solvent, the insoluble components precipitated are removed, and the solvent can be recovered from the resulting solution. A method for producing an optically isotropic pitch, which comprises obtaining a soluble component and heating the soluble component. |
