  • Method of optimizing mesophase formation in graphite and coke precursors
    Patent number: 4773985
    Abstract: Mesophase formation is optimized in graphite and coke precursors by a process which includes determining the values of critical chemical parameters for proposed precursors, modifying the precursors by adjusting such critical chemical parameters as oxygen content, aromaticity and functionality to within certain predetermined optimal limits and treating the resulting modified precursors to form mesophase. Oxygen content can be adjusted by oxidation or reduction of the precursor. Aromaticity can be adjusted by suitable heat treatment. Functionality can be adjusted by derivatization.
