The selective dehydration of fructose and sucrose to 5‐hydroxymethyl‐2‐furfural (HMF) has been achieved using heterogeneous Ge (IV) catalysts. Based on GeO 2 material, two catalyst systems are found to be efficient for the dehydration process. In the presence of the dual GeO 2 Ge 3 N 4 catalyst, fructose and sucrose was converted to HMF in 62 and 37% yield at 150°C for 100 min, respectively,. Moreover, with sulfated GeO 2 (SO 4 2− /GeO 2 ) as the catalyst, a 68% yield of HMF from the dehydration of fructose was obtained in dimethyl sulfoxide solvent. The effects of reaction temperature and reaction time were studied in the fructose dehydration. In addition, further investigations showed that dual GeO 2 Ge 3 N 4 catalyst is superior to SO 4 2− /GeO 2 for the conversion of sucrose to generate HMF under similar conditions. © 2014 American Institute of Chemical Engineers Environ Prog, 34: 207–210, 2015
