摘要： The invention provides a process to separate levulinic acid from a composition obtained by acid hydrolysis of biomass said process comprising subjecting said composition to solvent-solvent extraction to yield an organic phase comprising levulinic acid, and an aqueous phase; subjecting said organic phase to nanofiltration to yield a permeate comprising levulinic acid and a retentate; and recovering said permeate. The process is very suitable to remove any colour and humins (soluble tar), which would otherwise form a problem in subsequent process steps, particularly in distillation. Consequently, the process is simpler and results in higher yields of levulinic acid.

摘要： The invention provides a process for the isolation of levulinic acid and formic acid from a composition comprising formic acid and levulinic acid, said process comprising a solid-liquid separation step, a vapor removal step, and a solvent-solvent extraction step, wherein a vapor condensate vapor and/or an aqueous phase from the solvent extraction is used to wash the solid fraction. Washing with vapor condensate results in higher levulinic acid yields (higher levulinic acid recovery) as compared to washing with normal water. Washing with aqueous phase results in a less compressible filter cake. Washing first with aqueous phase and subsequently with condensate results in even higher levulinic acid yields. The process is suitable for isolating levulinic acid and formic acid from compositions made by acid hydrolysis of a lignocellulosic biomass, and also from compositions made by acid hydrolysis of sugars such as glucose and fructose.
