Abstract:
The variation of graphite properties with chemical structure is illustrated for synthetic graphites prepared from 35 pure aromatic compounds. Detailed chemical and physical studies have been directed to the carbonization of two model aromatic hydrocarbons, acenaphthylene, and 9,9'-bifluorenyl. These compounds exhibit extremes in graphitization behavior and the chemical reaction mechanisms are found to be consistent with the nature of the final graphitic products.

Carbonization studies have been extended to the effects of aromatic quinone additives on the carbonization behavior of polynuclear aromatic hydrocarbons. Quinones are shown to effect a general increase in coking value of the polynuclear aromatics and of complex aromatic mixtures. The mechanisms of these interactions are discussed.
