Derivation with acetic anhydride in aqueous media coupled with capillary gas chromatography mass spectrometry was used to distinguish alkyl anilines from alkyl pyridines. By use of this approach aniline, C-1 anilines, and C-2 anilines, as well as lesser quantities of C-2 pyridines and C-3 pyridines, were positively identified in a solvent refined coal (SRC)-II blended distillate and in an aqueous extract of the distillate. The extraction procedure and acetylation conditions employed were examined in detail and found suitable for quantitative analysis when combined with capillary gas chromatography. The SRC-II blended distillate contained 8200-9025 ..mu..g/mL anilines and 1335 /sup +/g/mL pyridines. Distilled water equilibrated with the distillate (1:100, SRC-II:H/sub 2/O) contained 65.9-78.9 /sup +/g/mL anilines and 5.6 /sup +/g/mL pyridines. 3 figures, 1 table.
