本文讨论了香草醛作为化学工业结构单元的用途。香草醛是目前仅有的以工业规模从生物质生产的分子酚类化合物之一。因此，它有可能成为合成生物基聚合物的关键中间体，其中芳香族单体需要达到良好的热机械性能。在第一部分致力于当前香草醛的来源后，本文重点介绍了碱性氧化木质素到香草醛的过程，报告的优点和局限性，讨论了产品分离的各种后解聚方法，最后探讨了香草醛作为化学工业关键构件的更广泛应用的前景。
The use of vanillin as a building block for the chemical industry is discussed in this article. Vanillin is currently one of the only molecular phenolic compounds manufactured on an industrial scale from biomass. It has thus the potential to become a key-intermediate for the synthesis of bio-based polymers, for which aromatic monomers are needed to reach good thermo-mechanical properties. After a first part dedicated to the current sourcing of vanillin, this article focuses on the alkaline oxidation lignin-to-vanillin process, reporting advantages and limits, discusses the various postdepolymerization methods for product isolation and finally examines the outlook for the wider use of vanillin as a key building block for the chemical industry.
