抄録

Wood lignins include guaiacyl (2-methoxyphenoxy)- and syringyl (2, 6-dimethoxyphenoxy)-types of aromatic nuclei, and their compositions are quite different in wood species, especially hardwood and softwood. In this work, thermal decomposition pathways of guaiacol (2-methoxyphenol) and syringol (2,6-dimethoxyphenol) were studied, which are models of guaiacyl- and syringyl-nuclei, respectively. Heat-treatment was conducted in a closed ampoule reactor under the conditions of N_2/ 600°C/ 40-600 s. From the present results, pyrolysis pathways of guaiacol and syringol were clarified, and additional OCH_3 group in syringol was found to result in higher coke formation reactivity. Roles of pyrolysis intermediates in coke and gas formation are also discussed.
