Abstract

See full text

Disclosed is a process for the extraction of furfural. The process includes subjecting a composition comprising furfural, water, at least one acid and an aromatic solvent, with a boiling point higher than that of furfural, to a first separation step in a first liquid-liquid separator providing a first organic phase and a first aqueous phase; conveying the first organic phase along a first line to a distillation column and subjecting the first organic phase to a distillation step providing a top stream comprising furfural and a bottom stream comprising the aromatic solvent; subjecting the first aqueous phase and a portion of the bottom stream to a second separation step providing a second organic phase; conveying the second organic phase along a second line which either feeds its contents into the first line or into the distillation column and subjecting the resultant mixture to said distillation step.
