A number of interesting nitrogen compounds have been identified in naphthalenic pitches and their extracts, viz. N-phenyl, N-methylphenyl, and N-(dimethylphenyl)phthalimides. Their structure has been derived from mass spectral analysis and confirmed by comparison with MS and elution data of the authentic standards prepared. Also discussed are the MS, NMR and chromatographic data of N-arylphthalimides and corresponding N-arylphthalisoimides.
