Direct transformation of fructose into 5-hydroxymethylfurfural (5-HMF) was carried out by using single or combination of catalysts like, MgF₂, MgTiO₃ and Mg (CF₃SO₃)₂ in a polar and biphasic solvent system under microwave assisted heating. We studied several metal catalysts but, the combination of Mg mediated catalysts were the most effective enabling up to 84% of 5- HMF yield from the fructose. We have developed a simple and eco-friendly method to the synthesis of 5-HMF for the industrial usage. Thus, the main advantage of current catalytic system based on cheap, readily abundant, recycled, reused and ecofriendly.

镁催化双相溶剂介导微波辅助合成5-羟甲基糠醛

果糖直接转化为 5-羟甲基糠醛 (5-HMF) 是通过使用单一或组合催化剂如 MgF ₂、MgTiO ₃和 Mg (CF ₃ SO ₃ ) ₂在微波辅助加热的极性和双相溶剂体系中进行的. 我们研究了几种金属催化剂，但 Mg 介导的催化剂的组合是最有效的，能够从果糖中获得高达 84% 的 5-HMF。我们开发了一种简单且环保的方法来合成工业用途的 5-HMF。因此，当前催化系统的主要优点是廉价、易得、可回收、可再利用和环保。
