The Distribution of Cigarette Smoke Components between Mainstream and Sidestream Smoke: III. Middle and Higher Boiling Components

Abstract

AbstractYields in sidestream smoke (SS) and mainstream smoke (MS) and sidestream smoke to mainstream smoke distribution ratios (SS/MS) of middle and higher boiling compounds, including neutral ones, were investigated for four types of unblended cigarette (bright, Burley, Turkish and domestic (cv. Matsukawa)). Both sidestream and mainstream smokes were separately collected with a combination of a glass fiber filter assembly, a small Elmenhorst cold trap and a liquid trap containing acetone cooled by dry ice - methanol. Of the 31 components quantitatively determined by gas chromatography, nicotine and acetic acid were the predominant components in both sidestream and mainstream smokes from all types of tobacco, followed by limonene, phenol, 3-vinylpyridine and 2-furaldehyde in sidestream smoke and neophytadiene, 3-hydroxypyridine, phenol and acetamide in mainstream smoke. The SS/MS ratios of the major compounds were as follows: pyridine, 10.2-13.3; limonene, 4.3-2.1; 3-picoline, 5.2-10.1; 2-cyclopentenone, 2.9-3.8; 2-furaldehyde, 4.9-7.4; pyrrole, 9.0-13.7; furfuryl alcohol, 3.0-4.8; acetamide, 0.8-1.7; 2.4-pentadien-4-olide, 5.2-8.9; neophytadiene, 1.0-1.8.
