使用自制的高温高压反应釜,在高温液态水（HTW）的条件下对木糖直接转化制备糠醛的过程进行了研究。考察了HTW作为反应介质对木糖转化率和糠醛产率的影响,并与文献中所采用催化剂的催化效果进行了对比,探索了不同的溶剂对反应产物中糠醛的萃取效果。研究结果表明：HTW作为反应介质对木糖直接转化制备糠醛具有优良的反应性能,可以替代液体酸和固体酸作用于木糖制糠醛,在优化的工艺条件下,当木糖初始浓度为10%（g/g）、反应温度为200℃、反应时间为3 h时,糠醛的产率高达78%。此外,乙酸丁酯作为萃取剂对于糠醛的萃取具有良好的萃取效率。所得结果为工业化生产糠醛奠定了实验基础和理论依据。

Direct conversion of xylose into furfural in high-temperature water（HTW） was carried out in a self-made high-pressure reactor.The effect of HTW as the reaction medium on xylose conversion and furfural yield was investigated,and was compared with others catalyst used in the literature.The effects of different solvents on the extraction of furfural were studied.The result showed that HTW was a perfect catalyst medium,which could replace liquid acid and solid acid in the conversion of xylose into furfural.The optimal furfural yield of 78% was obtained at a reaction temperature of 200 ℃,a holding time of 3 h and initial xylose concentration of 10%.In addition,furfural could be well extracted by n-butyl acetate.Therefore,a novel approach to furfural production is presented,providing a basis as well as technical parameters for its commercialization.
