Using metal halides as catalyst and alkali metal halides as co-catalyst catalyzed glucose to dehydrate to make 5-hydroxymethylfurfural(5-HMF).Under the condition that the mass ratio of the material and catalyst is 10∶1 and the mass ratio of the material and co-catalyst is 1∶1,the following observations and studies were made on the influence of the metal halides、co-catalyst、solvent、temperature and time on the yield of 5-HMF.The results showed that,when NaI was used as co-catalyst for the AlCl3-catalyzed conversion of glucose at 130℃for 15 min in N,N-Dimethylacetamide (DMAC) the yield of 5-HMF is up to 30.6%.
