Abstract
The invention discloses a method for preparing 2, 5-furandicarboxylic acid (FDCA) by using sodium hypochlorite to perform electro-catalysis on 5-hydroxymethylfurfural (5-HMF). The method is characterized by comprising the following steps: evenly mixing the 5-HMF, the sodium hypochlorite and an alkaline solution at the room temperature to obtain a mixed solution, and mixing the mixed solution intoan anode electrolytic cell; adding an alkaline solution into a cathode electrolytic cell, wherein the volume of the added alkaline solution is equal to that of the mixed solution, and the molar concentration of the added alkaline solution is equal to that of solute of the alkaline solution in the mixed solution; taking an anode material as an anode electrode, and carrying out a reaction for 1-12hunder the condition that the potential is 1.0-2.0V so as to obtain the FDCA. The method first uses the sodium hypochlorite and electrolyzed effective chlorine component thereof as an oxidizing agent,takes cheap metals and metal compounds as the anode electrode, replaces the traditional precious metal-based electrode material catalyst with an oxidation reaction catalyst, and replaces the traditional high temperature and high pressure thermal catalytic reaction with a mild electrooxidation reaction at room temperature and atmospheric pressure, so that the cost is greatly lowered, the reaction process is simplified, the energy is saved, the conversion rate of the 5-HMF is further increased, the yield and selectivity of the FDCA are approached, and the industrial production of the FDCA is promoted.
