摘　　要：己二腈是一种重要的有机化工中间体.己二腈加氢后可制备己二胺,主要用于生产尼龙-66,故而市场应用前景巨大.传统的己二腈合成方法需要使用大量的石油原料,具有很多的发展制约.因此,近年来,以非石油原料合成制备己二腈的研究备受关注.本文对目前已发表的关于非石油原料合成己二腈的研究成果进行了总结,包括基于生物质、煤基和其他可再生资源的合成方法以及使用酶催化、电催化、化学催化等不同的合成策略.本文还结合现有的路线汇总了当前有望被开发的反应路径,并探讨了未来可能的研究方向和应用前景.需要强调的是,开发具有自主知识产权的己二腈合成工艺对于我国尼龙-66产业的发展至关重要,如何有效地开发新型己二腈合成技术将是未来面临的重大挑战.本文对非石油原料合成己二腈的研究进行了展望,为相关产业的路线设计和开发提供参考.Adiponitrile is the precursor for nylon-66 production,and its synthesis relies heavily on petroleum resources.In recent years,fluctuating oil prices and geopolitical factors have caused huge uncertainty in adiponitrile supply,severely hindering the stable development of nylon-66 industry.Hence,scientists in China have been motivated to explore alternative synthesis routes from non-petroleum resources with independent intellectual property rights.This issue has been selected as one of the top ten industrial technology issues of the China Association for Science and Technology in 2022,reflecting the urgency and significance of the research topic.Conventional adiponitrile synthesis methods generally suffer from high energy consumption and complex processes.Even after years of optimization,the most advanced direct cyanide method for butadiene still cannot avoid the problem of waste generation.Moreover,foreign corporations have accumulated extensive experiences through long-term deficit operations,which continuously improved the technology and reduced costs.Simply following existing processes can hardly make any breakthrough.Thus,completely new synthesis strategies must be developed to achieve the technological advancements.In recent years,a variety of new techniques such as microreactor synthesis,advanced catalyst design,and coproduction technology emerged,and they have provided novel ideas for the design of the new adiponitrile synthesis routes.Thus,it is necessary to comprehensively analyze the recent progresses to identify the core scientific challenges.By conducting fundamental research to tackle these problems,it is promising to transform the advanced but immature strategies into practical processes.This paper comprehensively reviews the latest research progresses on adiponitrile synthesis from non-petroleum feeds,systematically summarizing various synthesis strategies based on renewable resources like biomass,coal and natural gas,as well as different methods employing enzymatic,electrochemical,and chemical cata
