  • This study was conducted to evaluate the characterization of the pyrolysis products of tobacco constituents such as cellulose, lignin and tobacco additives. The pyrolysis condition was designed to simulate the pyrolysis/distillation zone$(200\~600^{\circ}C)$ and combustion zone$(700\~950^{\circ}C)$of burning com in the smoking cigarette. The pyrolysis products were determined by GC/MS after pyrolysis using Double-Shot pyrolyzer. In the case of cellulose and lignin, the number of pyrolysis product in the condition that simulate the pyrolysis/distillation zone was much more than the combustion zone simulating one. The major products of cellulose were levoglucosan, furfural, and 1, 6-anhydro-$\beta$-D-glucofuranose and that of lignin were phenol, 2-methoxy phenol, and 1, 2-dimethoxy benzene. In the case of tobacco additives such as 2, 6-dimethyl pyrazine, maltol, and piperonal, the pyrolysis products of these additives were evaporated from the pyrolyszer at least $96\%$ intactly. These results indicate that tobacco constituents such as cellulose and lignin were thermally degraded at the pyrolysis/distillation zone and thoroughly broke down at the combustion zone, but tobacco additives were intactly evaporated from burning com of smoking cigarette.

  • 담배향료로 사용하는 코코아 분말을 Cigarette smoking condition인 distillation-pyrolysis zone과 high temperature zone중에서 4개의 온도 35$0^{\circ}C$, 55$0^{\circ}C$, $650^{\circ}C$, 85$0^{\circ}C$를 선택하여 열분해 장치를 이용하여 열분해하였고, 열분해생성물은 CS2 trap과 charcoal tube로 포집하여 GC/MS분석에 이용하였다. 분석 결과 $650^{\circ}C$에서 열분해가 가장 잘 이루어졌고 수율 역시 가장 높았다. 열분해의 주요 성분은 주로 hydrocarboil과 phenolic화합물이 90%이상을 차지하였고 그 외에 소량의 aldehyde, ketone, pyrazine도 검출되었다. 열분해 온도에 따라서 성분의 변화를 보면 decane, styrene, tridecane, m-cresol,4-ethylphenol등은 증가하였고, hexadecane, tetradecane등은 감소하였다. 또 o-cresol, 2-ethylphenol등은 함량변화가 거의 없었다.
