摘要：
The hydrocarbons of primary brown-coal tar have been separated by vacuum fractionation, liquid chromatography, and the formation of adducts with urea and thiourea into classes of compounds differing by the type of carbon skeleton and degrees of aromaticity and of condensation. The hydrocarbon fractions obtained have been studied by IR and UV spectroscopy, chromato-mass spectrometry, emission spectral, elementary, and functional analyses, cryoscopy, and capillary gas chromatography. The contribution to the primary brown-coal hydrocarbons of high-molecular-weight olefins of normal and iso structures, including isoprenoid compounds and cycloparaffins with long aliphatic chains has been established.
