    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 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: US0118523ng 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 460 ~C (about 550 ~F - 932 ~F). At least 80 % of the carbon atoms of the hydrocarbo ns are aromatic as characterized by carbon 13 NMR. The aromatic hydrocarbons ar e selected from a group consisting of aromatic compounds having 2 to 5 aromati c 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 compound having 2 to 5 rings wherein said substituents are alkyl groups having 1 to 3 carbons, and mixtures thereof.

    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.
