โœฆ Synopsis

Coals of increasing rank contain a mixture of solid fragments and particles which look liquid. The first ones are a fractions insoluble in boiling anthracene-oil, the others are /I fractions (soluble in anthracene-oil but insoluble in toluene). The content of fi fraction passes by a maximum as softening during pyrolysis. This fraction is responsible for coal behavior in heat-treatment.

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
