Abstract: In order to investigate the effects of pyrolytic temperature on the aromatic components in cigarette smoke,the cut filler of Virginia type cigarette was pyrolyzed in an air flow of 30 mL/min at the programming temperatures started from 50℃ for 20 s and then increased to 400℃,600℃,800℃,1000℃ and 1200℃ at the rate of 10℃/ms respectively,and held at the end temperature for 20 s.The aromatic components in pyrolytic products released at different pyrolytic conditions were analyzed by gas chromatography/mass spectrometry.The results showed that:1)57,70,76,77 and 68 kinds of aroma components were identified in the pyrolyzates at 400℃,600℃,800℃,1000℃ and 1200℃,respectively;2) the deliveries of aromatic components increased with the increase of pyrolytic temperature from 400℃ to 1000℃,increased by 24% from 400℃ to 600℃,by 1% from 600℃ to 800℃,by 8% from 800℃ to 1000℃,and decreased from 1000℃ to 1200℃;3) the dominant aromatic components at different pyrolytic temperatures were:furones and pyrones,aldehydes,phenols,alcohols,acids and esters at 400℃,alkenes and nicotine at 600℃;nicotine derivatives including myosmine,nicotyrine,etc at 800℃;ketones,nitrogen heterocyclics,furans and benzofurans at 1000℃;4) nicotine delivery increased with the increase of pyrolytic temperature in the range of 400℃ to 600℃,and decreased slightly thereafter.It seemed that the flavor of cigarette smoke would change with burning temperature.
