The pyrolytic behavior of vanillin, a flavorant for manufactured cigarettes, was examined to find its contribution to the smoke composition. Vanillin was pyrolyzed at various temperatures (500-$900^{\circ}C$) in a stream of nitrogen. Pyrolytic products at $800^{\circ}C$ were identified with GC/MS. As increasing temperature, pyrolytic products did not appear with qualitative differences. Component analysis of the resulting products showed that 24 compounds were identified. and phenolic compounds were major products. The pyrolytic pathway of vanillin was also discussed.
