Abstract:
A process for the extraction of furfural from a composition comprising furfural, water, at least one organic acid and an oxygenate solvent with a boiling point higher than that of furfural. The process includes: (a) subjecting the composition to a first liquid-liquid separation step to provide: (i) an organic phase; (b) subjecting the organic phase of step (a) to a first distillation step to provide: (i) a first top stream; (c) subjecting the first top stream of step (b) to a second liquid-liquid separation step to provide: (i) a second top stream; and (d) subjecting the second top stream of step (c) to a second distillation step to provide: (i) a third top stream comprising a furfural-water azeotrope, and (ii) a third bottom stream comprising furfural.

Claim (Index 8):
The process according to  claim 1 , wherein the second bottom stream of step (c) comprising a portion of the furfural and a portion of the at least one organic acid is subjected to a third distillation step to provide a fourth top stream comprising a portion of the furfural, and a fourth bottom stream comprising water and the at least one organic acid.
