如果木质素优先的生物炼制概念成为现实，那么与天然木质素结构接近的高质量木质素将大量生产。利用这种可再生材料的一种潜在方法是通过解聚生成芳香化学品。这就需要发展新的化学方法。在这里，我们报告了先进木质素模型聚合物的合成和表征，作为开发这些方法的工具。木质素中主要键的控制结合被证明可以得到复杂的硬木和软木木质素模型聚合物。这些聚合物已经通过二维HSQC NMR和GPC分析进行了表征，并与分离的木质素进行了比较。
If the lignin-first biorefinery concept becomes a reality, high quality lignins close in structure to native lignins will become available in large quantities. One potential way to utilise this renewable material is through depolymerisation to aromatic chemicals. This will require the development of new chemical methods. Here, we report the synthesis and characterisation of advanced lignin model polymers to be used as tools to develop these methods. The controlled incorporation of the major linkages in lignin is demonstrated to give complex hardwood and softwood lignin model polymers. These polymers have been characterised by 2D HSQC NMR and GPC analysis and have been compared to isolated lignins.
