Abstract

A method of converting a lignocellulosic biomass to monosaccharides, and optionally further converting the monosaccharides to one or both of furfural and HMF, includes contacting the biomass with a reactive liquid phase comprising LiBr, H2SO4, and water, wherein H2SO4 preferably constitutes at most 1.0 wt %, more preferably at most 0.5 wt %, and most preferably at most 0.1 wt % of the reactive liquid phase, and water preferably constitutes at most at most 60 wt %, more preferably at most 50 wt %, and most preferably at most 30 wt % of the reactive liquid phase.
