系统地研究了反应气氛对离子液体1-乙基-3-甲基咪唑氯（[C2mim][Cl]）中木材液化解聚的影响。木材样品在120°C下用[C2mim][Cl]在氧气、氮气和二氧化碳等不同气氛下进行干燥和加湿处理。处理后的残渣百分比表明，在[C2mim][Cl]中，氧气对木材的液化有明显的促进作用，在任何气氛下，湿度对木材的液化几乎没有影响。凝胶渗透色谱（GPC）和高效液相色谱（HPLC）对[C2mim][Cl]中溶解化合物的分析表明，氧气和湿度促进了木材组分的解聚。由此可见，反应气氛对木材在[C2mim][Cl]中的反应有影响，并有控制作用。
The influence of reaction atmosphere on the liquefaction and depolymerization of wood in an ionic liquid, 1-ethyl-3-methylimidazolium chloride ([C2mim][Cl]), has been systematically studied. The wood samples were treated with [C2mim][Cl] at 120°C under various atmospheres such as oxygen, nitrogen, and carbon dioxide, both dried and humidified. The percentage of residue after the treatment shows that oxygen considerably accelerates the liquefaction of wood in [C2mim][Cl], and humidity hardly affects liquefaction under any atmosphere. Gel permeation chromatography (GPC) and high performance liquid chromatography (HPLC) analyses on the solubilized compounds in [C2mim][Cl] indicate that oxygen and humidity enhance the depolymerization of the wood component. Thus, the reaction atmosphere was revealed to influence, and 1be capable of controlling, the reaction of wood in [C2mim][Cl].
