采用H2SO 4浸渍法制备了硫酸化氧化锆，并采用BET比表面积、XRD、TG-DTA和FNR等技术对硫酸化氧化锆进行了表征。以硫酸化氧化锆为催化剂，微波加热果糖脱水制备5-羟甲基糠醛（5-HMF）。在丙酮-二甲基亚砜（DMSO）混合溶剂中，在180 ℃下反应20 min，硫酸化氧化锆催化剂可使果糖转化率达到93.6%，5-HMF收率为72.8%。在非水溶剂中，硫酸化氧化锆是果糖合成5-HMF的有效催化剂，但在水溶剂中催化活性较低。(C)2009爱思唯尔有限公司版权所有。
Sulfated zirconia was prepared by impregnation with H2SO4, and was characterized using BET Surface area, XRD, TG-DTA and FNR techniques. The sulfated zirconia was evaluated as a catalyst for the dehydration of fructose to 5-hydroxymethylfurfural (5-HMF) by microwave heating. With sulfated zirconia catalyst, high fructose conversion of 93.6% with 5-HMF yield of 72.8% could be attained at 180 degrees C for 20 min reaction time in acetone-dimethylsulfoxide (DMSO) mixtures. Sulfated zirconia is an effective catalyst for producing 5-HMF from fructose in non-aqueous solvent but shows low catalytic activity in water solvent. (C) 2009 Elsevier B.V. All rights reserved.
