✦ Synopsis

Extracts from various coals and coal-derived

products were studied using liquid chromatography with optical activity detection. Thechromatogramsshow that there are substantial numbers of optically active components in these samples. Since both dextrorotatory and laevorotatory components are present, some mutual cancellation would result if only the bulk optical rotation were measured. The chromatograms are generally rich in structure and contain distinct features which may be good fingerprints for establishing the origins of the coals and monitoring coal processing.
