Title (EN) PROCESS FOR THE RECOVERY OF FURFURAL
(FR) PROCÉDÉ DE RÉCUPÉRATION DE FURFURAL
Abstract: front page image
(EN)Disclosed is a process for the extraction of furfural including: (a) subjecting a composition comprising furfural, water, at least one inorganic acid, at least one organic acid and a solvent mixture comprising an aromatic solvent and an oxygenate solvent, to a first separation step providing: (i) a first organic phase; (b) subjecting the first organic phase to a first distillation step providing: (i) a first top stream comprising furfural and a portion of the at least one organic acid; (c) subjecting the first top stream from step (b) to a second separation step providing: (i) a second top stream enriched with furfural; (d) subjecting the second top stream from step (c) to a second distillation step providing: (i) a third top stream comprising a furfural-water azeotrope, and (ii) a third bottom stream comprising furfural.
(FR)L'invention concerne un procédé d'extraction de furfural comprenant : (a) soumettre une composition comprenant du furfural, de l'eau, au moins un acide inorganique, au moins un acide organique et un mélange de solvants comprenant un solvant aromatique et un solvant oxygéné, à une première étape de séparation fournissant : (i) une première phase organique ; (b) soumettre la première phase organique à une première étape de distillation fournissant : (i) un premier flux supérieur comprenant du furfural et une partie dudit au moins un acide organique ; (c) soumettre le premier flux supérieur de l'étape (b) à une seconde étape de séparation fournissant : (i) un second flux supérieur enrichi en furfural ; (d) soumettre le second flux supérieur de l'étape (c) à une seconde étape de distillation fournissant : (i) un troisième flux supérieur comprenant un azéotrope de furfural-eau, et (ii) un troisième flux inférieur comprenant du furfural.
