将冷冻处理前后的日本柳杉边材在400℃下进行炭化,得到了木醋液、木焦油和木炭.与没有处理相比,虽然处理过边材的木焦油的收率几乎不变,木醋液的收率显示增加倾向,但是木炭的收率有减少迹象.用毛细管气相色谱法对得到的木醋液中的11种成分进行了定量分析.与无处理相比较后,发现处理过边材木醋液中的甲醇、脂肪酸及糠醛(呋喃甲醛)的收量有了变化,但是5-羟甲基糠醛、麦芽酚、苯酚、邻苯二酚及愈创苯酚的收量几乎没有变化.%Sugi sapwoods at different moisture content after and before freezing treatment were carbonized at 400 ℃ to afford wood-vinegar, wood-tar and charcoal. Yield of wood-vinegar prepared from the treated wood tended to increase, and yield of charcoal indicated opposite tendency, but yield of wood-tar was almost constant. 11 components in wood-vinegar obtained from the Sugi sapwoods after and before treatment were determined by capillary gas chromatography (capillary GC). The change in amounts of methanol, carboxylic acids and 2 - furaldehyde in wood-vinegar from the treated sapwood was observed, but amounts of 5 - hydroxymethyl - 2 - furaldehyde, maltol, phenols, pyrocatechol, and guaiacols were almost constant.
