A method involving acid extraction, fractionation, derivatization and g.c.-m.s. analysis was used to characterize the basic nitrogen compounds in coal tar. It was found that these compounds fall into ten compound types belonging to eighteen homologous series. Separation of aza-arenes from amines by

โฆ Synopsis
The basic components contained in a coal liquefaction product obtained from the Wilsonville, Alabama coal liquefaction pilot plant were examined by means of capillary-column chromatographic-mass spectroscopy. A total of 62 of the 150 components observed were identified. The most interesting of the newly identified compounds are phenoxazine, butyl quinolines and isoquinolines, diarylamines and aminobiphenyl derivatives. The possibility of removing amino aromatics from coal liquefaction products by condensing them with the phenols in the mixture is discussed.
