英文摘要	acid-promoted, selective production of 5-hydroxymethylfurfural (hmf) under high fructose concentration conditions was achieved in ionic liquids (ils) at 80 degrees c. a hmf yield up to 97% was obtained in 8 min using 1-butyl-3-methylimidazolium chloride ([c(4)mim]cl) catalyzed with 9 mol % hydrochloric acid. more significantly, an hmf yield of 51% was observed when fructose was loaded at a high concentration of 67 wt % in [c(4)mim]cl. water content below 15.4% in the system had little effect on hmf yield, whereas a higher water content was detrimental to both reaction rate and hmf yield. in situ nmr analysis suggested that the transformation of fructose to hmf was a highly selective reaction that proceeded through the cyclic fructofuranosyl intermediate pathway. this work increased our capacity to produce hmf, and should be valuable to facilitate cost-efficient conversion of biomass into biofuels and bio-based products.
