With the gradual depletion of fossil energy , non-renewable energy is increasingly scarce . 5 - hydroxymethylfurfural is an important chemical platform chemicals from renewable biomass resources Preparation of 5 - (hydroxymethyl) furfural and broad prospects , and 5 - (hydroxymethyl) furfural can be subjected to further reaction to generate fuel to ease the energy crisis . Microcrystalline cellulose as raw materials , the ionic liquid 1 - Butyl 3 - methyl chloride imidazole (BMIMCl) as a solvent , the metal chloride as a catalyst , a low temperature under atmospheric pressure , the preparation of 5 - (hydroxymethyl) furfural . The effects of a single factor amount of water added , the amount of sulfuric acid , the reaction temperature , reaction time, a different catalyst and concentration of raw materials the yield of the product 5 - (hydroxymethyl) furfural , determine the reaction concentration of the best material for the microcrystalline cellulose , and the ionic liquid mass ratio of 1:10, and the reaction catalyst is a mixture of chromium chloride, and copper chloride , both the molar ratio is 4:1 . Orthogonal test was designed to determine the optimal conditions for the the feedstock preparation of 5 - (hydroxymethyl) furfural microcrystalline cellulose : reaction temperature of 150 ° C , reaction time 4h, the quality of the water and microcrystalline cellulose ratio of 1:1 , sulfuric acid and micro- crystalline cellulose , the mass ratio of 0.025 moles of 5 - (hydroxymethyl) furfural , the yield was 43.41% . This paper further wheat straw as raw material , the ionic liquid 1 - butyl 3 - the methyl chloride imidazole (BMIMCl) as solvent , chloride, chromium and copper chloride mixture as a catalyst , prepared 5 - (hydroxymethyl) furfural furfural. The effects of the concentration of raw materials , wheat straw, grain size , reaction temperature, reaction time, hydrochloric acid concentration on the yield of the reaction product to determine the optimum concentration of raw materials is 1:10 , wheat straw particle size of 20 mesh to 40 mesh . By orthogonal experiment to determine the optimal conditions for wheat straw as raw materials Preparation of 5 - (hydroxymethyl) furfural : reaction temperature of 170 ° C , the reaction time of 2 h , hydrochloric acid , and wheat straw mass ratio of 0.09 , in reaction conditions 5 - (hydroxymethyl) furfural molar yield of 48.02% , 20.31% molar yield of furfural is .
