Conversion of plant biomass, such as hemicellulose, provides a sustainable pathway toward renewable fuels. Using 1-ethyl-3-methylimidazolium chloride and Brønsted acid catalysts, hemicellulose was hydrolyzed to monosaccharides in an 85 wt% yield, with 5 wt% dehydration products and 4 wt% humins, under stepwise water addition. Adding 1,4-dioxane eliminated humin formation.
