✦ Synopsis

Gas chromatography (g.c.), in conjunction with nitrogen-selective alkali flame detection (AFD) and mass spectrometry (m.s.), has been used for the detailed examination of nitrogen compounds in basic fractions from an anthracene oil and a low-temperature coal tar. The compounds identified were mainly aza species, but some di-nitrogen and mixed heteroatomic compounds were detected in the anthracene oil bases. Nitrogen-selectiveg.c.AFD chromatograms of the extraction residuesshowed complex mixtures of non-basic nitrogen compounds; the major peaks were identified, but further g.c.-m.s. investigation of these compounds will require the preparation of hydrocarbon-free fractions.
