| Abstract: | 5-Hydroxymethylfurfural is a new kind of platform chemical with many excellent properties. The reaction of the production of 5-hydroxymethylfurfural using sucrose as raw material under micro- wave irradiation was studied.And the effects of reaction temperature,catalyst concentration,sub- strate concentration and reaction time on HMF yield were investigated.The optimal reaction condi- tions were obtained as follows:temperature 433.15 K,sulfuric acid concentration 0.15 mol/L,su- crose concentration 12%,and reaction time of 6min.Under the optimal conditions,the HMF yield and selectivity were 32.4% and 36.2%,respectively.Under the microwave irradiation,the reaction time can be reduced to 6 min. |
