近年来,由生物质生产呋喃衍生产品已成为一个热点研究领域,因其是有助于构建实现可持续能源供应和生产替代化学品的主要途径之一。作为一种重要的呋喃衍生品,2,5-二甲酰基呋喃是一种具有潜在广泛应用前景的多功能有机中间体。虽然2,5-二甲酰基呋喃已被证明非常有用,但其在工业上仍不易获得。迄今为止,已有很多催化方法可用于2,5-二甲酰基呋喃的制备,但多为化学催化法,环境污染大。电催化氧化法制备2,5-二甲酰基呋喃利用电化学反应的优势,是一种清洁氧化技术。本文介绍了电催化氧化技术应用于制备2,5-二甲酰基呋喃的主要反应途径及机制;对其技术优势和存在的问题也作了较为详细的阐述;并结合其研究现状对选择性电催化氧化制备2,5-二甲酰基呋喃技术进行了展望。总之,所述方法能够为未来工业上通过该清洁氧化技术而不是常见的化学催化法进行2,5-二甲酰基呋喃的生产提供一条潜在的可行的转化途径。

In recent years, the production of furan derivatives from biomass has become an exciting research field, because it contributes to building one of the major routes for achieving sustainable energy supply and the production of alternative chemicals. As one of the most important furan derivatives, 2,5-diformylfuran (DFF) is a multifunctional organic intermediate with the prospective app- lication potentiality in the future. Although it has been proven very useful, DFF is still not easy to be obtained in industry. Up to now, there are several catalytic methods available for the preparation of DFF, but mainly concentrated on chemical catalysis, which are prone to bring about serious environmental pollution. Preparation method for producing DFF through electric-catalytic oxidation, taking the advantages of the electrochemical reaction, is a kind of clean oxidation technology. Main reaction routes and mechanisms of the electric-catalytic oxidation technology applied to the preparation of DFF were introduced;its technical advantages as well as existing problems were also elaborated;and combined with its research status, the technology of preparation of DFF through selective electric-catalytic oxidation was prospected. In a word, the introduced method could provide a potentially feasible transformation path for the industrial production of DFF through this kind of clean oxidation technology, instead of common chemical catalysis.
