Abstract

Catalytic dehydration of glucose and fructose into 5-Hydroxymethylfuran (5-HMF) catalysed by sulfated zirconia in 1-butyl-3-methylimidazolium chloride ([BMIM][Cl]) ionic liquid was investigated by reactive vacuum distillation process.  A 5-HMF yields of 82% and 65% were obtained using fructose and glucose substrates in 2 h reaction time at 180 oC. When the reaction time was increased beyond 2 h, a decreased in 5-HMF yield was observed. The ionic liquid and sulfated zirconia exhibited a constant activity when recycled for five successive trials. This process provided an avenue whereby the production of 5-HMF from cassava-derived carbohydrate is conducted and separated with minimal use of volatile solvents.
