化学降解是从木质素中提取生物油和其他化合物的有效方法。木质素生物油是酚醛树脂中酚组分的潜在替代品。在这里，我们开发了一种基于高分辨率质谱的分析方法，为合成的木质素衍生树脂提供了结构信息，并支持其性能的预测。以典型木质素降解产物为基础，采用电喷雾负离子模式对不同模型树脂进行了分析。利用增强的质量缺陷过滤技术提供了详细的结构信息的木质素为基础的模型树脂，并很容易补充差示扫描量热法和热重分析的分析数据。苯酚替代品的相对反应性和化学多样性是PF树脂合成结果的重要决定因素，从而控制了所得聚合物的应用领域。
Chemical degradation is an efficient method to obtain bio-oils and other compounds from lignin. Lignin bio-oils are potential substitutes for the phenol component of phenol formaldehyde (PF) resins. Here, we developed an analytical method based on high resolution mass spectrometry that provided structural information for the synthesized lignin-derived resins and supported the prediction of their properties. Different model resins based on typical lignin degradation products were analyzed by electrospray ionization in negative ionization mode. Utilizing enhanced mass defect filter techniques provided detailed structural information of the lignin-based model resins and readily complemented the analytical data from differential scanning calorimetry and thermogravimetric analysis. Relative reactivity and chemical diversity of the phenol substitutes were significant determinants of the outcome of the PF resin synthesis and thus controlled the areas of application of the resulting polymers.
