Abstract:
Disclosed is a process for the extraction of furfural which includes: (a) 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 providing: (i) an organic phase, and (ii) an aqueous phase; (b) subjecting the aqueous phase of step (a) to a first distillation step to provide: (i) a first in top stream comprising a furfural-water azeotrope; (c) subjecting the first top stream of step (b) to a second separation step to provide: (i) a second top stream comprising a portion of the furfural-water azeotrope; (d) subjecting the second top stream of step (c) to a second distillation step to provide: (i) a third top stream enriched with the furfural-water azeotropic mixture; (e) subjecting the organic phase of step (a) to a third distillation step to provide: a fourth top stream comprising furfural.

Claim (Index 2):
The process according to  claim 1 , wherein the composition is derived from a product stream of a pentose dehydration step wherein a pentose feed stream is dehydrated.
