Mesophase pitch, recognized as an essential precursor for high performance carbon fiber was prepared from a petroleum pitch by carbonizing under vacuum conditions at 430 degree C for 5 h. The solubility and melting temperature were 55 wt% in quinoline and 270 degree C, respectively at complete development anisotropic mesophase pitch. This solubility is much higher than that of mesophase pitch from the same feedstock using refluxing and gas blowing conditions. Yields of the mesophase pitch of complete anisotropic development were 60 wt% under vacuum. Structure of these mesophase pitches were analyzed.
