“…Hartung and Jewell (6) used alumina adsorption, perchloric acid extraction, and spectrophotometric examination to identify indoles, carbazoles, phenazines, and dibenzofuran in a hydrogenated, catalytically-cracked furnace oil. The same authors also reported (7) the use of zinc chloride and ferric chloride as complexing agents for the isolation of nitriles from a hydrogenated furnace oil. Carbazole was identified in Wilmington, Calif., petroleum by Helm and coworkers (9) using distillation, adsorption, chemical treatment, gas chromatography, and spectrometry.…”

“…Cyanonaphthalenes have not been found in combustion effluents before. They have, however, been found at trace levels in cigarette smoke tar (14,15), in petroleum (16), in tar from the low-temperature pyrolysis of coal (17), and in anthracene oil (18). In all of these cases, it is presumed that cyanonaphthalenes are formed from the pyrolysis of other nitrogen compounds (19).…”

Cyanonaphthalenes (both isomers) and cyanoacenaphthylenes (four isomers) were identified in the soot generated by the combustion of aromatic hydrocarbon fuels doped with 6-30% pyridine. These were by far the most abundant nitrogen-containing organic compounds in this combustion effluent; multiring, nitrogen heterocyclic compounds, such as those commonly observed in airborne particulate matter, were a minor component. These identifications were made by gas chromatographic mass spectrometry following a preliminary separation by alumina column chromatography. The environmental significance of these findings is discussed.Certain organic compounds in soot cause cancer in man (1).

“…Greater sensitivity (0)(1)(2)(3)(4)(5) Although it gives reproducible and accurate values for most oils and additives, it is a lengthy procedure, especially where large samples must be decomposed for low-level nitrogen contents. An alternative procedure is the Dumas technique which has found most use in the microchemical laboratory.…”
