The utilization of lignin and glyoxal as potentially sustainable and less hazardous building blocks for phenolic resins is an emerging research field. Lignin thereby serves as a partial, macromolecular substitute for phenol, while glyoxal fulfills the role of an aldehyde cross-linker. In the first part of this perspective, the industrial context of lignin and glyoxal will be expounded with a focus on their origin and production processes. In the framework of phenolic resins, the use of lignin and glyoxal can be categorized into two research domains: (i) glyoxalation to improve the reactivity of lignin prior to resin synthesis and (ii) direct resin synthesis using lignin and glyoxal with glyoxal immediately serving as the cross-linker. This perspective provides a comprehensive overview of the progress made in both domains, pinpointing the opportunities, blind spots, and challenges that lay ahead.

使用木质素和乙二醛的生物基树脂

木质素和乙二醛作为酚醛树脂的潜在可持续发展和危害较小的构建基块的利用是一个新兴的研究领域。因此，木质素充当酚的部分大分子替代物，而乙二醛起醛交联剂的作用。在此观点的第一部分中，将阐述木质素和乙二醛的工业背景，重点是其来源和生产过程。在酚醛树脂的框架内，木质素和乙二醛的使用可分为两个研究领域：（i）乙二醛化以提高木质素在树脂合成之前的反应性；（ii）使用木质素和乙二醛直接与乙二醛直接合成树脂作为交联剂。此观点提供了这两个领域所取得进展的全面概述，
