热处理温度对橡胶木材淀粉含量的影响
|
摘要
以水蒸气作为保护气,将橡胶木分别于125、145、165、185℃处理2h,采用高氯酸法测定热处理橡胶木中的淀粉含量。研究表明,橡胶木素材中的淀粉含量高达11.681%,经过高温(125、145、165、185℃)处理后,其淀粉含量逐步降低。当热处理条件为125、145、165、185℃/2 h时,测出相应的淀粉含量分别为8.792%、8.500%、7.529%、4.386%。结果表明,橡胶木中的淀粉含量随着热处理温度的升高而下降。FTIR谱图分析表明淀粉发生降解。
The starch content changes of thermally modified rubberwood, which was treated at 125, 145, 165, 185 ℃for 2 h, respectively, were assayed using perchloric acid. The starch content of fresh rubberwood was 11.681%, but it was significantly reduced after thermal modification. When the thermal treatment temperature was 125, 145, 165, 185 ℃/2 h, the starch content was 8.792%, 8.500%, 7.529%, 4.386%, correspondingly. The results indicated that the starch content of rubberwood decreased as the thermal treatment temperature increased. Starch was degraded during thermal treatment, and no new functional groups were detected through FTIR analysis.
