In this work, D001-cc cation-exchange resin was modified by CrCl3 using an ion exchange method to obtain a Cr3+-D001-cc catalyst. FT-IR, UV-vis, SEM, EDX, ICP-OES and Py-IR were used to characterize the catalyst. Subsequently, the effects of the modified metal ion and different cation-exchange resin on the direct conversion of glucose to 5-hydroxymethylfurfural in [Bmim]Cl were examined. The results showed that Cr3+-D001-cc resin exhibited excellent catalytic performance. Moreover, with Cr3+-D001-cc resin as a catalyst, the influence of the reaction conditions on the dehydration of glucose was investigated in detail. 61.3% yield of 5-hydroxymethylfurfural was achieved in the [Bmim]Cl ionic liquid at 110 degrees C for 30 min with 0.1 g catalyst. Finally, a recycling experiment was performed. The result indicated that the HMF yield in the Cr3+-D001-cc resin and [Bmim]Cl system significantly decreased after six recycles.
