Associated with the Preparation of Pitch Precursors

1 Mechanisms associated with the preparation of pitch precursors 

The degree of graphitic character can be established using X-ray techniques and Simon et al [84,85] showed that in the carbonization of anthracene, the average structure of the resultant products for the mesophase stage was represented by condensed anthracene dimers (bisanthene), whilst at 600°C, the average structure for the coke was

A number of structures, as determined by field desorption mass spectroscopy (FDMS), for polymeric products obtained by the pyrolysis of anthracene have been proposed by Lewis [86], where molecular weights up to 1400 have been identified
