摘要：

The components of the volatile fraction of a coal tar pitch were studied by capillary gas chromatography and combined gas chromatography-mass spectrometry using the OV-1701 stationary phase in both instances. The temperature-programmed retention indices and the molecular weight of each identified compound are given. It is shown that the volatile fraction of the coal tar pitch is composed of a group of homologous series of polycyclic aromatic compounds.
