| titleOfInvention | Method for continuously preparing 2, 5-furandicarboxylic acid by using microchannel reaction device |
| abstract | The invention discloses a method for continuously preparing 2, 5-furandicarboxylic acid by using a microchannel reaction device, which comprises the following steps: dissolving 5-hydroxymethylfurfural and 2,2,6, 6-tetramethylpiperidine-N-oxide in water, and dropwise adding acetic acid to prepare a homogeneous solution A; dissolving sodium bromide and sodium chlorite in water to prepare a homogeneous solution B; dissolving sodium hydroxide in water to prepare a homogeneous solution C; respectively and simultaneously pumping the homogeneous phase solution A and the homogeneous phase solution B into a first micro-mixer, and introducing into a first micro-reactor; simultaneously, pumping the homogeneous solution C and the effluent of the first microreactor into a second micromixer respectively and simultaneously, introducing the mixed solution into a second micro-reaction device, and collecting the effluent to obtain a product. The method uses sodium chlorite as an oxidant, and has the advantages of low oxidant price, moderate reaction temperature, high yield, good target product selectivity and the like. Meanwhile, the method has the advantages of simple operation, low cost, continuous production and good industrial application prospect. |
