| titleOfInvention | A kind of method utilizing biomass carbohydrate to prepare 5-methylfurfural |
| abstract | The invention relates to a method for preparing 5-methylfurfural by utilizing biomass carbohydrates, comprising the following steps: adding biomass carbohydrates, tungsten carbide, distilled water, hydroiodic acid or elemental iodine, and an organic solvent into a reactor in sequence, Under a hydrogen atmosphere of 50-500 psi, at a temperature of 90-200°C, stir the reaction for 15-180 minutes, cool in an ice-water bath, separate the reaction liquid, separate the upper organic phase, and obtain 5-methylfurfural after further purification. The raw materials for the preparation of 5-methylfurfural in the present invention mainly come from renewable biomass carbohydrates; cheap and recyclable tungsten carbide catalysts are used and carried out under mild reaction conditions, which reduces production costs and does not require high production equipment , in line with the principle of safe production. |
