Summary
A rapid method is described for the determination of hydrocarbon groups in coal liquids. Analysis is carried out by high-performance liquid chromatography on a LiChrosorb NH2 column with n-hexane as the mobile phase. The separation is controlled only by the number of double bonds in a given hydrocarbon molecule. It is essentially independent of the molecular mass for a large variety of compounds investigated. Example of the separation of hydrogenated derivatives of anthracene and of a coal liquid fraction are presented.
