中文摘要：

引言 与石油路线以“三烯三苯”作为平台化合物类似，生物质资源路线需要建立自己的平台化合物体系，其中5-羟甲基糠醛（5-hydroxymethylfurrural，5-HMF）、乙酰丙酸（1evulinicacid，LA）等被认为是适宜的平台化合物，因而开发绿色催化体系实现从生物质资源出发高效、高选择性地制备这些平台化合物是关键。

英文摘要：

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·L^-1.The results showed that their conversion went up with the increase of reaction temperature and catalyst concentration,resulting in higher yield of levulinic acid.By comparing the correlation coefficients,it was confirmed that both glucose and 5-hydroxymethylfurfural decomposition are first order reaction.By 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,respectively.This 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.
