平台化合物5-乙氧甲基糠醛的最新研究进展

Advances in Bio-Based Platform Chemical 5-Ethoxymethylfurfural

近年来,随着化石资源的急剧消耗和能源需求的日益增长,寻找替代能源以减少社会对石油化工产品的依赖成为人类社会面临的共同难题。因此,如何最大程度的利用可再生自然资源引起了越来越多的关注。到目前为止,许多科研机构和公司在开发新的生物质化学品以及新的生产方法方面做了大量的工作。在自然界储量极为丰富的生物质成为最具吸引力的潜在能源。5-乙氧甲基糠醛(EMF),经实验证明可作为柴油添加剂或者直接替代柴油作为生物燃料使用,是相当有前途的第二代生物燃料。从目前的研究结果来看,EMF是以乙醇作为溶剂,从果糖、葡萄糖或者蔗糖等单糖或多糖得到。在大多数的合成机理中,EMF的合成都需要经过一个HMF的中间体过程。本文对EMF的独特性质、形成机制以及近年来的研究结果进行了综述研究,重点概括了近五年来该领域的重大合成进展,对其今后的研究方面提出了建议。

In the recent years, interest in making the best use of renewable natural resources, to reduce society＇s reliance on synthetic petroleum - based chemicals, is increasing due to the depleting supply of fossil fuels with the simultaneous increase in energy demand. Currently, there is an enormous amount of work being done by both academic and industrial institutes to develop both new bio - based chemicals and innovative bio - based routes to existing chemicals. Biomass is the most attractive sustainable feedstock, as it is widely available and renewable. 5 - Ethoxymethylfurfural （EMF） is a promising second - generation biofuel, which has been tested as a possible additive or even substitute for diesel fuel. EMF can be synthesized from 5 - hydroxymethylfurfural （HMF） in ethanol or from fructose, glucose or sugarcane through an HMF intermediate. The unique property of EMF, the formation mechanism and tile results of recent research studies are reviewed, especially focusing on the significant progress in this field during the past five years. Finally, some suggestions on the future research are given.
