| Abstract: | The effect of bi-promoters on preparation of 5-hydroxymethyl furfural(5-HMF) from glucose catalyzed by AlCl3 was studied.The influence of the types and dosages of the promoters was investigated,and the reaction conditions were also optimized.The results showed that using double promoters of NH4Br-NaBr,the yield of 5-HMF increased remarkably.Under the condition of 0.08 mol·L-1 NH4Br-0.32 mol·L-1 NaBr,reaction temperature 100 ℃,reaction time 60 min,the yield of 5-HMF was up to 54%,which was 21 percent point higher than that over single AlCl3 catalyst. |
