The decomposition kinetics of glucose and 5-hydroxymethylfurfural catalyzed by copper chloride were measured in small volume high-pressure vessel batch reactors,at various temperatures from 423.15 K to 463.15 K and catalyst concentration from 0 to 0.08 mol·*** results showed that their conversion went up with the increase of reaction temperature and catalyst concentration,resulting in higher yield of levulinic *** comparing the correlation coefficients,it was confirmed that both glucose and 5-hydroxymethylfurfural decomposition are first order *** using first order kinetics equation,the activation energies of desired and undesired reaction were estimated,134.65 kJ·mol-1 and 144.1 kJ·mol-1 for glucose decomposition,131.97 kJ·mol-1 and 135.18 kJ·mol-1 for 5-hydroxymethylfurfural decomposition,*** work would provide important basic data not only for the exploration of reaction mechanism of glucose decomposition,but also for the development of high activity and high selectivity catalyst.
