Abstract: The present invention provides a process for obtaining a very clean mesophase pitch from isotropic pitch. This invention utilizes a solvent fractionation process which does not involve the process steps, yield loss and waste generation associated with fluxing and filtering the isotropic pitch. Additionally, this invention provides a liquid/liquid extraction process that avoids the solids handling and the high temperatures and pressures of supercritical fluid extraction. Finally, this invention controls the hardness of the mesophase product.

Abstract: The present invention provides a process for thermosetting pitch fibers in reduced times, at low concentrations of oxygen and at higher temperatures than previously possible. Additionally, the present invention provides a pitch fiber which has an oxygen diffusion rate to the center of the fiber which is competitive with the rate of oxidation at the fiber's surface. Further, the present invention provides a high density pitch fiber batt which thermosets without loss of fiber structure.

Abstract: This invention provides a process for preparing a solvated isotropic pitch having a fluid temperature at least 40 ~C lower than the same pitch in the nonsolvated state. Additionally, the present invention provides a solvated isotropic pitch which may be formed into carbon artifacts which do not require oxidative stabilization prior to carbonization.
