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。 In the experiment, vacuum high temperature heat treatment method was used to conduct the high temperature heat treatment of African tropical wood lutea mulberry with temperature of 220 ℃ and time of 8h. The acetone extract of Lonicera morifolium before and after heat treatment was analyzed by GC / MS. The results showed that the content of the chromophore groups such as ester, methoxy, carbonyl and other chromogenic groups in the extract increased obviously when the heat treatment led to the oxidation and reduction reaction of the wood extract. The color of the heat treated wood changed obviously.
