糠醛氧化合成糠酸

Preparation of Furoic Acid by Oxidation of Furfural

糠酸作为糠醛的重要下游产品,在食品制造、材料制备、光学技术、药物合成中具有重要的应用,可用于合成防腐剂、增塑剂、热固性树脂、香料以及多种药物。目前,关于糠醛的制备以及催化氢化制备下游产物的综述报道相对较多,但是还没有系统地整理评述糠醛氧化合成糠酸的相关工作。本文综述了近年来以糠醛为主要原料制备糠酸的研究进展情况,讨论了不同催化体系及在不同氧源存在下对糠酸选择性的影响,重点突出了非均相催化剂在糠酸的工业化制备中的应用前景,对糠酸制备的未来发展方向进行了展望。

As an important downstream product of furfural, furoic acid has important applications in food manufacturing, material preparation, optical technology and drug synthesis. It can be used to synthesize preservatives, plasticizers, thermosetting resins, spices and a variety of drugs. At present, there are many reviews on the preparation of furfural and the preparation of downstream compounds by hydrogenation. However, there is no systematic review on the oxidation of furfural to furoic acid. This paper reviews the progress in preparation of furoic acid from furfural in recent years. The effects of different catalytic systems and different oxygen sources on the selectivity of furoic acid are discussed. The application prospect of heterogeneous catalysts in the preparation of furoic acid is highlighted, and the future development direction of furoic acid preparation is prospected.
