    Abstract: PURPOSE: To provide a new method for producing a unique metal-containing isotropic pitch material that is suitable for production of carbon fiber. CONSTITUTION: A soluble aromatic organometallic compound is added to a carbon starting material that is substantially defective in the meso phase pitch, the resultant mixture is subjected to the heat soaking to give the isotropic pitch containing mesogen and soluble organometallic compound. Then, the pitch products are subjected to the solvent separation to separate the mesodiene containing the metal from the organometallic compound. This metal-containing mesogen is heated up to sufficiently elevated temperature and fused to form the metal-containing mesophase pitch. In another process, the carbon starting material is thermally soaked to form isotropic pitch product containing mesogen. A high-molecular-weight soluble aromatic organometallic compound is added to the mesogen-containing isotropic pitch product, then subjected to the solvent separation. The metal-containing carbon fiber produced from the mesophase pitch shows increased stability and tensile strength. Alternatively, the solvent fractionation or separation is carried out under supercritical conditions to form metal-containing mesophase pitch. The formulation of the organometallic compound to the carbon source may be done either of before or after thermal soaking.

    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.
