Abstract:

A natural attapulgite (ATP)-based catalyst, sulfated In2O3-ATP (SO42-/In2O3-ATP), was obtained by an impregnation-calcination method and was used to efficiently and selectively produce the useful platform chemical 5-hydroxymethylfurfural (HMF) from hexoses. Some important reaction parameters were studied, revealing that Lewis and Brönsted acid sites on SO42-/In2O3-ATP catalyze glucose isomerization and fructose dehydration. The yields of HMF from glucose and fructose were 40.2% and 46.2%, respectively, using the optimal conditions of 180 ℃ for 60 min with 10 wt% of solid acid catalyst in a mixture of γ-valerolactone-water (9:1).
