| Abstract: | An efficient process for preparation of 5-hydroxymethylfurfural (5-HMF) from cellulose was carried out using ionic liquid 1-methyl-3-methyl-imidazole dimethyl phosphate (DMIM]DMP]) as reaction medium, extremely low 0.1% mixed acids (0.1%,maleic acid and HCl) as catalyst.Yield of 5-HMF was 29.13% and conversion efficiency was 6.48mg/min. The reaction condition of microwave was 720W for 9min at 240℃.The ratio of solid to liquid was 1:50(mass ratio) and acid concentration was 0.1%. |
