摘要：2,5-Furandicarboxylic acid (FDCA) is an important monomerfor thebio-based degradable polymer polyethylene 2,5-furandicarboxylate.Current kinetic studies on the preparation of FDCA by the liquid-phaseoxidation of 5-hydroxymethyl furfural (HMF) have failed to quantitativelyconsider the effect of the ratio and concentration of Co/Mn/Br ternarycatalysts, although they play an important role in the oxidation reactionrate and selectivity. In this work, an effective collision theorywas introduced into the kinetic modeling, and then, a kinetic modelof HMF oxidation with nine parameters was developed. The fitting resultsof this model using experimental data of HMF liquid phase oxidationwith different catalysts and temperatures were satisfactory. The relativecollision frequency coefficients & alpha; and & beta; successfullydescribe the reactivity of Co and Mn, respectively, and they are onlyinfluenced by the water content in the solvent and do not vary withtemperatures. The chain initiation rate constants are only temperature-dependent,and the other rate constants remain constant over the studied range.The kinetic model developed in this work would bring valuable insightsinto the synergistic effects of the Co/Mn/Br ternary catalyst componentson the oxidation of HMF.
