Abstract: | As a key renewable chemical for plastics and fine chemicals, the preparation of 5-hydroxymethylfurfural (5-HMF) from biomass
is an important research topic. Cellulose, although abundant in nature, is difficult to convert to 5-HMF in good yields due
to its recalcitrant and heterogeneous nature. In this work, we show an efficient two-step process for converting microcrystalline
cellulose into 5-HMF with ionic liquids under mild conditions. In the first step, high glucose yields of above 80% could be
obtained from the cellulose hydrolysis by a strong acidic cation exchange resin in 1-ethyl-3-methyl imidazolium chloride (EMIM]Cl])
with gradual addition of water. In the second step, the resin was separated from the reaction mixture and CrCl3 was added which lead to a 5-HMF yield of 73% based on cellulose substrate. The strategy can allow practical conversion of
biomass into bio-derived products. |
