摘要：

Six vitrinite-concentrated coal samples were treated with NaOH-alcohol at 300 or 350 °C for 1 h. The products were nearly all soluble in pyridine except those from the oldest coal (52.4% of extraction yield). Structural indices of these pyridine extracts were calculated from ultimate analytical values, molecular weight and 1H-n.m.r. data. The younger coals have tetralin-type nuclei and bituminous coal has 5-6 rings, about 2 of naphthene type. The younger coals were estimated to have more frequent ether linkages. © 1979.
