SOLUTE-ENHANCED PRODUCTION OF GAMMA-VALEROLACTONE (GVL) FROM AQUEOUS SOLUTIONS OF LEVULINIC ACID |
| 摘要 |
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. |

1. A method to isolate levulinic acid (LA), the method comprising:
(a) providing an aqueous solution comprising LA and a sufficient concentration of a water-soluble solute to yield a solution that is substantially immiscible with gamma-valerolactone (GVL); and (b) extracting LA from the aqueous solution of step (a) using an extraction solvent comprising GVL. |
