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

The yield of quinoline-insoluble portion from pitches correlates well with the aromatic hydrogen content of the carbon disulphide-soluble fraction scaled up by proportion to the whole pitch, which therefore by implication is an indication of the binding properties. The chemical shifts are explained
Abstr anthracene chars heat treated between 500 and 1200ยฐC 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
