The lignin by‐product of the conversion of lignocellulosic biomass to 5‐(chloromethyl)furfural (CMF) has been characterised by thermogravimetric analysis, N2 physisorption porosimetry, attenuated internal reflectance IR spectroscopy, elemental analysis and solid‐state NMR spectroscopy. The lignin (LCMF) has a moderate level of mesoporosity before thermal treatment and a surface area of 63 m2 g−1, which
木质纤维素生物质转化为5-(氯甲基)糠醛(CMF)的木质素副产物已通过热重分析,N 2物理吸附孔隙率法,衰减内反射红外光谱,元素分析和固态NMR光谱进行了表征。木质素(LCMF)在热处理之前具有中等水平的介孔性,表面积为63 m 2 g -1,在高于400°C的温度下热解时急剧增加。通过分析在一定热解温度范围内进行热处理的LCMF,可以评估材料的功能和质构特性。将样品磺化以测试其在乙酰丙酸酯化中作为多相酸催化剂的潜力。结果表明,未热解的催化剂具有高达93%的最高酯收率。据我们所知,这是介孔木质素具有明显表面积的第一个例子,该表面积直接由生物精炼工艺生产,并经过进一步的材料改性。
