Abstract:
A method to produce levulinic acid (LA) and γ-valerolactone (GVL) from biomass-derived cellulose by selective extraction of LA by alkylphenol (AP) and hydrogenation of LA, in which mineral acid used in the method is recycled and the final concentration of GVL is increased by successive extraction/hydrogenation steps to allow for effective separation by distillation.
