Chromatography of 2,4-Dinitrophenylhydrazones of Some Aldehydes and Ketones in Tobacco Smoke

Air Pollution in Diesel Bus Garages

“…Aldehydes were known to be present in exhaust fumes and, as acrolein is notorious for its lachrymatory properties even in extremely low concentration, it was thought that the eye irritation might have been caused by this substance. Acrolein could not be detected, however, by separating on paper sheets the 2 : 4-dinitrophenyl hydrazine derivatives of aldehydes (Buyske, Owen, Wilder, and Hobbs, 1956) which were collected from bus exhausts on another occasion, although other aldehydes and ketones could be identified readily. The quantities of aldehydes collected in the main experiments were insufficient for such detailed analysis but this work is continuing.…”

Isolation and ldentification of 2,6- Dimethyl- and 2,2,6 -Trimethyl-4-piperidone, Artifacts Produced by the Reaction of Cigarette Smoke Condensate and Acetone

“…A methanol/cyclohexane partition (see Figure 2) followed by gc analysis showed no evidence of [1] (<0.1 !lg/cigarette) in the polar fraction. These results suggest that a large excess of acetone is required to form significant amounts of [ 1] since there is some acetone present in fresh smoke from both Burley and Bright cigarettes (16). The effect of other parameters on the yield of [ 1] was also investigated.…”
