摘要：

Addition of tetracyanoethylene or p-phenylenediamine to CS2-NMP mixed solvent markedly increased the extraction yield for Upper Freeport coal (86 wt% C). The presence of atmospheric oxygen during extraction decreased the yield. The pyridine-insoluble fraction of the extract was most affected. No such large effects were observed for other coals. The mechanisms responsible are discussed.
