| Abstract: | 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. |
