Studies on cellulose cigarette smoke. IV. Carbonyl compound composition of cellulose cigarette smoke condensate.

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.
