Abstract
A process for producing mesophase pitch, the process including: contacting an isotropic pitch with a solvent under conditions sufficient to produce a solvent fraction comprising the solvent and an insoluble fraction comprising mesophase pitch; and recovering the mesophase pitch, wherein the contacting includes the solvent having a Solubility Blending number (SBN) that causes the mesophase pitch to have a softening point ranging from 270° C. to 350° C., as measured in accordance with ASTM D3104-14.
