Don) sapwood, Charcoal, Wood-Vinegar, Capillary gas chromatography, capillary GC, Carbonization Abstract Sugi sapwoods treated with aqueous acetic acid were carbonized at 400 ℃ for 1h under nitrogen gas to afford wood-vinegar, wood-tar and charcoal. Yield of the wood-vinegar was increased by treatment with aqueous acetic acid, and yields of the wood-tar and the charcoal were decreased. Eleven components in the wood-vinegar were determined by capillary gas chromatography (capillary GC). Amounts of 5-hydroxymethyl-2-furaldehyde and 2- furaldehyde in the wood-vinegar were increased after the acid treatment, but amounts of carboxylic acids, phenols, pyrocatechol, guaiacols, and maltol were almost constant. A mixture of sugi sapwood and charcoal as an additive was carbonized at 400 ℃ for 1h under nitrogen gas. Amounts of acetic acid and propionic acid in the wood-vinegar were increased with the increase in charcoal amount. On the other hand, amounts of furans, maltol, phenols, pyrocatechol and guaiacols were decreased. departmental bulletin paper 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2003-07 VoR application/pdf 宮崎大学工学部紀要 32 73 77 Memoirs of Faculty of Engineering, University of Miyazaki AA00732558 05404924 https://miyazaki-u.repo.nii.ac.jp/record/2398.1/files/KJ00002425488.pdf http://hdl.handle.net/10458/245 https://miyazaki-u.repo.nii.ac.jp/records/2398 jpn
