Abstract
In the course of systematic studies of cellulose cigarette smoke, carbonyl compounds extracted with aqueous sodium bisulfite solution were examined and 63 compounds-15 furans, 13 cyclic ketones, 8 lactones, 7 benzene derivatives, and 20 aliphatic ketones, aldehydes and other compounds-were either positively or tentatively identified. Of these 63 compounds, 45 were identified for the first time in this study in cellulose pyrolyzate. Semi-quantitative estimation of some of these compounds revealed that 2-hydroxy-3-methyl-2-cyclopenten-1-one (cyclotene) was the most abundant, followed by 1-hydroxy-2-propanone (acetol), 2-furaldehyde, 1-hydroxy-2-butanone, cyclopentan-l, 2-dione, etc., in decreasing order. Compo-unds possessing pleasant caramel-like odor were found to be relatively abundant both in number and quantity.
