Highly efficient production of 2,5-dihydroxymethylfuran from biomass-derived 5-hydroxymethylfurfural over an amorphous and mesoporous zirconium phosphonate catalyst

论文摘要

The development of high-efficiency and low-cost catalysts is very crucial for the MeerweinPonndorf-Verley(MPV) reduction of biomass-derived 5-hydroxymethylfurfural(HMF) into 2,5-dihydroxymethylfuran(DHMF). In this work, an amorphous and mesoporous zirconium phosphonate catalyst(Zr-DTMP), which is a zirconium-containing organic-inorganic nanohybrid, was successfully designed and synthesized by the simple assembly of zirconium tetrachloride(ZrCl4) and diethylene triaminepenta(methylene phosphonic acid)(DTMP). Satisfactorily, when Zr-DTMP was employed for the MPV reduction of HMF in the presence of 2-butanol(sec Bu OH), DHMF yield could be achieved as 96.5% in 3 h under a relatively mild reaction temperature of 140 ℃. Systematic investigations indicated that this high catalytic activity should be mainly due to the cooperative role of enhancive Lewis acid site(Zr4+)and Lewis base site(O2-) in activating the carbonyl group of HMF and dissociating the hydroxyl group of sec Bu OH, respectively. Additionally, Zr-DTMP showed excellent catalytic stability, when it was successively used 5 recycles, its surface characteristics and textural properties still remained almost unchanged, and so, the catalytic activity was not obviously affected. More interestingly, Zr-DTMP could also be applied for the selective reduction of other biomass-derived carbonyl compounds, such as 5-methylfurfural(MF),furfural(FF), levulinic acid(LA), ethyl levulinate(EL) and cyclohexanone(CHN), into the corresponding products with high yields, which is beneficial to the effective synthesis of various valuable bio-based chemicals.
