Abstract: The catalytic effects of phosphate, sulfuric acid, zinc acetate and sodium hydroxide catalysts on the preparation of 5-hydroxymethylfurfural(5-HMF) were investigated with maltose as raw material and water as solvent, and the results showed that the catalytic capacity of sodium hydroxide was much higher than that of other catalysts and the dosage was less. Response surface methodology(RSM) was utilized for optimization the reactive conditions with the yield of 5-HMF as yardstick. The optimum values of these factors were found to be as follows: reaction temperature 95.20 ℃, mass of sodium hydroxide 2.25 g, reaction time 6.17 h. In this case, the yield of 5-hydroxymethylfurfural reached 61.13%.The result of infrared spectrogram analysis was consistent with the standard sample,and 5-HMF was prepared from maltose.

Key words: 5-hydroxymethylfurfural, maltose, response surface methodology(RSM), carbohydrate
