Solute-enhanced production of gamma-valerolactone (GVL) from aqueous solutions of levulinic acid

Patent ·
OSTI ID:1170743
A method to produce levulinic acid (LA) and gamma-valerolactone (GVL) from biomass-derived cellulose or lignocellulose by selective extraction of LA using GVL and optionally converting the LA so isolated into GVL, with no purifications steps required to yield the GVL.
