Description

Technical field [0001] The present invention relates to a method for preparing 2,5-furandicarboxylic acid by catalytic oxidation of 5-hydroxymethylfurfural in aqueous phase. Specifically, the method uses bismuth compound-supported Pt or Pd particles as a catalyst, and air or oxygen is used as an oxygen source. Water is the solvent to realize efficient oxidation of 5-hydroxymethyl furfural to 2,5-furandicarboxylic acid. Background technique [0002] The contradiction between the reduction in the total amount of fossil resources such as coal, oil, and natural gas and the rapid increase in human demand for energy has become increasingly significant, and it is urgent to seek renewable alternative resources. Biomass resources are considered to be very potential clean, renewable alternative resources. The preparation of chemicals through the conversion of sugar compounds is an important process in biomass conversion. 5-Hydroxymethylfurfural is an important platform compound in sugar ...
