RESEARCH AND DEVELOPMENT ON ADVANCED GRAPHITE MATERIALS VOLUME XXVII-CARBONIZATION STUDIES OF POLYNUCLEAR AROMATIC HYDROCARBONS

摘要

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 re action 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 poly nuclear aromatics and of complex aromatic mixtures. The mechanisms of these interactions are discussed.This technical documentary report has been reviewed and is approved.
