STUDIES ON CELLULOSE CIGARETTE-SMOKE .6. COMPOSITION OF THE WATER-SOLUBLE PORTION OF CELLULOSE CIGARETTE-SMOKE CONDENSATE

Water-soluble portion of the smoke condensate of cellulose cigarette was studied and 42 compounds—10 lactones, 6 cyclopentanones (or cyclopentenones), 5 pyrans and other compounds—were either positively or tentatively identified. Of these 42 compounds, 12, such as succinaldéhyde, 5-hydroxy-2-pentenone, etc., were identified for the first time in cellulose pyrolyzate. Semi-quantitative estimation of some of the major components in water-soluble portion revealed that 1, 6-anhydroglucopyranose (levoglucosan) was the most abundant, followed by 2-hydroxy-3-methyl-2-cyclopentenone (cyclotene), acetol, 2-hydroxy- 5-pentanolide, etc. Glycolaldéhyde which seems to be more abundant than cyclotene on chromatogram could not be estimated because of peak tailing. Of these water-soluble components, succinaldéhyde has very pungent and irritating effect and seems to be a cause of the pungent and irritating odor of cellulose cigarette smoke. © 1979 Taylor and Francis Group, LLC.
