✦ Synopsis

Shpol'skii luminescence spectra in straight-chain-alkane matrices at 77 K have been measured from carbon-disulphide extracts of nine coal macerals and a cyclohexane extract of a coal-tar pitch. Twelve individual polycyclic hydrocarbons, containing from three up to ten rings, have been identified. The Shpol'skii effect, which requires little pretreatment of the sample, is particularly sensitive (0.1 ppm) to the carcinogen benz[al pyrene.

Thermogravimetric analysis techniques have been adapted to study the thermal decomposition of six coal tar pitches. Two material constants are introduced to describe the thermal stability and/or reactivity of coal tar pitches. These constants can be correlated with the softening point of the pitches
