    Abstract: La presente invencion describe un proceso para obtener una pez mesofásica muy limpio a partir de pez isotropico. Esta invencion utiliza un procedimiento de fraccionamiento mediante disolvente, el cual no involucra las etapas de proceso, pérdidas de rendimiento, y generacion de desperdicio asociadas con la adicion de fundentes y filtracion de la pez isotropico. Adicionalmente, esta invencion provee un proceso de extraccion líquido/líquido que evita el manejo de solidos y las altas temperaturas y presiones de la extraccion de fluidos supercrítica. Finalmente, esta invencion controla la dureza del producto mesofásico.

    Abstract: This invention relates to low melting solvated mesophase pitches which are suitable for spinning into carbon fibers. The solvated mesophase pitches have a lower melting point than conventional mesophase pitch but remain substantially anisotropic. The solvated mesophase can be produced as an intermediate during solvent fractionation or supercritical solvent fractionation of mesogen-containing isotropic pitches. The process is enhanced through the ability to recover pseudomesogens with an increased average molecular weight which, in combination with the solvent content, provides a fusible mesophase capable of being spun directly into infusible oriented anisotropic carbon fibers.

    Abstract: A solvating component for a solvated mesophase pitch. The solvated component includes a mixture of aromatic hydrocarbons having boiling points in the atmospheric equivalent boiling point range of about 285° to about 500° C. (about 550° F.-932° F.). At least 80% of the carbon atoms of the hydrocarbons are aromatic as characterized by carbon 13 NMR. The aromatic hydrocarbons are selected from a group consisting of aromatic compounds having 2 to 5 aromatic rings, substituted aromatic compounds having 2 to 5 aromatic rings wherein said substituents are alkyl groups having 1 to 3 carbons, hydroaromatic compounds having 2 to 5 rings, substituted aromatic compounds having 2 to 5 rings wherein said substituents are alkyl groups having 1 to 3 carbons, and mixtures thereof.

    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.
