摘要:
 为进一步研究沙柳木材苯酚液化的最佳制备工艺，以苯酚为液化剂，稀硫酸为催化剂，对沙柳木材进行液化试验，研究反应温度、催化剂用量、液比和反应时间对液化率的影响，并借助FTIR技术分析了沙柳木材及其液化产物的成分。结果表明，对沙柳木材苯酚液化影响最大的因素是液比，其次是反应温度、催化剂用量、反应时间；沙柳木材苯酚液化较适宜的试验条件是：液比7∶1，反应温度160℃，催化剂加量10%，反应时间120 min。沙柳木材液化后，红外谱图上出现了新的特征峰，说明木粉中化学组分的分子结构发生了变化，形成了更多的官能团。
Abstract:
 In order to develop optimal preparation technological procedure for the liquefaction of Salix wood,taking phenol as a liquefier,diluted sulfuric acid as a catalyst,effects of relative factors on the rate of liquefaction were investigated,such as reaction temperature,amount of catalyst,ratio of liquefier,and reaction time.Liquefier ratio exhibited the strongest influence on the liquefaction process,followed by reaction temperature, amount of catalyst,and reaction time.The optimal conditions were as follows:liquid ratio 7∶1,temperature 160℃,10% of catalyst,liquefaction time 120 min.FTIR analysis demonstrated that the molecular structure of Salix wood powder underwent significant changes,indicating the success of the liquefaction.
