摘要
试验采用真空高温热处理方法,对非洲热带木材绿柄桑进行温度为220℃、时间为8h的高温热处理,采用气-质联用对热处理前后绿柄桑木粉的丙酮抽提物进行分析。结果表明,热处理使木材抽提物发生氧化、还原反应,抽提物中的酯基、甲氧基、羰基等发色基团的物质含量明显增多,使热处理材颜色发生明显变化。
The Okan was thermal modified at temperature 220℃ and duration 8h by vacuum. Analysis was done by GC/ MS to the acetone extract of control and treated specimen wood flour. The results show that the extract occurred oxidation- reduction reaction as a result of heat-treatment. The content of ester group, methoxyl group and carbonyl group increased, which made the color of the Okan floor changed obviously.
