摘要：
Petroleum ether insoluble and chloroform soluble fractions of pyridine extracts from various coals were separated by liquid chromatography and solvent extraction. The products thus obtained were analyzed by nuclear magnetic resonance and infrared spectroscopy. The analytical data were used to calculate the aromacity of the original coals. The estimated aromacities showed good agreement with values obtained by other methods.
