摘要

The Makerwal coal of Pakistan gives higher extractibility with Tetrahydrofuran (THF) as compared to Sharigh, Sor-Range and Lakhra coals. The structural characterization of Pakistan coal extracts by FT-IR spectroscopy indicates that all the extracts contained less condensed aromatic rings in comparision to their original coal.
