| 摘 要： | 目的]研究玉米秆在超临界乙醇条件下的解聚产物。方法]采用FTIR和GC/MS分析解聚产物。结果]超临界乙醇解聚产物成分十分复杂,GC/MS分析鉴定出89种有机化合物,其中72种为含氧化合物,主要有酯、酚、醚、酮和醇等,还检测出少量烷烃、烯烃、芳烃、苯硫酚和含氮化合物,反映了解聚产物的高含氧量和低含氮硫量的特性。其中42.7%乙酯类可能是C12-C30的饱和脂肪酸、部分不饱和脂肪酸、邻苯二甲酸或苯丙酸等与乙醇酯化的结果;而22.9%的苯酚和苯二酚类物质、芳烃类及甲氧基苯类物质可能来源于木质素在超临界乙醇中的解聚作用。结论]玉米秆的超临界乙醇解聚产物成分十分复杂,乙醇参与了玉米秆的超临界解聚反应。
