摘要：

After preextraction with ethanol-benzene (1:2) in a Soxhlet apparatus Tuncbilek lignite was extracted with dioxane at 330 degrees C in an autoclave at different pressures and for different exposure times. The extracts were fractionated and many of the compounds they contain were identified by gas chromatography/mass spectrometry. The formation and yields of these compounds are discussed in terms of the structure of the parent fuel and the mechanism of extraction.
