Abstract

Shengli lignite was subjected to thermal dissolution in a methanol/benzene mixed solvent at 240°C for 1 h. The soluble fraction was sequentially eluted with petroleum ether and 5, 10, and 15% carbon disulfide/petroleum ether mixed solvents through a silica gel-packed column to afford eluted fractions 1 to 4 (EF₁ to EF₄). In total, 15 methyl alkanones from C ₁₅ to C₂₇, including 2 methyl side-chain alkanones and 13 methyl straight-chain alkanones were enriched in EF₄ and identified with gas chromatography/mass spectrometry.
