Carbonization of oxidized mesophase pitches originating from petroleum and coal tar was examined by thermogravimetry, FT-i.r. spectroscopy, and quantitative analysis of evolved gases. Polymerization and condensation of aromatic rings through loss of aromatic hydrogen are shown to be major chemical r

Abstr anthracene chars heat treated between 500 and 1200°C is developped and applied to d.c. electrical conductivity, paramagnetic susceptibility and apparent density. An inhomogeneous process for the carbonization is proposed, in agreement with recent results on the structure of these chars. acts 3

QI-free coal tar pitch is separated into a toluene-soluble (TS) and a toluene-insoluble (TI) fraction by solvent extraction. The effect of controlled mixing of both fractions on mesophase formation is studied. The formation of mesophase is correlated with the carbon and hydrogen contents of the samp
