We report a biorefining strategy to separate levulinic and formic acids (obtained from cellulose hydrolysis) from aqueous solutions of H2SO4 employing reactive extraction using butene to produce esters of levulinic and formic acids, which spontaneously separate from H2SO4 and can be converted to γ-valerolactone over a dual-catalyst-bed system (Pd/C+Ru/C).
