Adipic acid (AA) is a key industrial dicarboxylic acid intermediate used in nylon manufacturing. Unfortunately, the traditional process technology is accompanied by serious environmental pollution. Given the growing demand for adipic acid and the desire to reduce its negative impact on the environment, considerable efforts have been devoted to developing more green and friendly routes. This Review is focused on the latest advances in the sustainable preparation of AA from biomass-based platform molecules, including 5-hydroxymethylfufural, glucose, γ-valerolactone, and phenolic compounds, through biocatalysis, chemocatalysis, and the combination of both. Additionally, the development of state-of-the-art catalysts for different catalytic systems systematically is discussed and summarized, as well as their reaction mechanisms. Finally, the prospects for all preparation routes are critically evaluated and key technical challenges in the development of green and sustainable processes for the manufacture of AA are highlighted. It is hoped that the green adipic acid synthesis pathways presented can provide insights and guidance for further research into other industrial processes for the production of nylon precursors in the future.
己二酸（AA）是一种用于尼龙制造的关键工业二羧酸中间体。不幸的是，传统的工艺技术伴随着严重的环境污染。鉴于对己二酸的需求不断增长，以及减少其对环境的负面影响的愿望，人们投入了相当大的努力来开发更绿色、更友好的路线。本综述重点介绍了通过生物催化、化学催化以及两者结合，从基于生物质的平台分子（包括 5-羟甲基糠醛、葡萄糖、γ-戊内酯和酚类化合物）可持续制备 AA 的最新进展。此外，还系统地讨论和总结了不同催化体系的最先进催化剂及其反应机理。最后，对所有制备路线的前景进行了批判性评估，并强调了绿色和可持续制备 AA 的关键技术挑战。希望所提出的绿色己二酸合成途径能为未来尼龙前体生产的其他工业过程的进一步研究提供见解和指导。
