Research on the catalytic conversion of cellulose into 2,5-dimethylfuran

  • Received Date: 2019-02-03
  • The ionic liquids of 1-butyl-3-methylimidazolium chloride and 1-sulfopropyl-3-methylimidazolium hydrogensulfate were used as solvents and catalysts respectively to hydrolyze cellulose. Then using formic acid as hydrogen source, 2,5-dimethylfuran(DMF) was prepared by catalytic hydrogenation.According to the UV absorption spectrum of the standard samples and Lambert Beer's law,quantitative and qualitative analysis methods for DMF were established to select suitable DMF preparation conditions. The results showed that when the concentration of formic acid was 2 mol·kg-1, the reaction temperature was 343 K and the time was 12 h, the yield of DMF reached a maximum of 41.2%. Compared with the traditional method, the use of ionic liquid enhanced the stability of the system, reduced the specific gravity of the organic solvent, and the reaction process was greener.
