Title (EN) PROCESS FOR FURFURAL PRODUCTION FROM BIOMASS
(FR) PROCÉDÉ DE PRODUCTION DE FURFURAL À PARTIR DE BIOMASSE
Abstract: front page image
(EN)Furfural is produced from a lignocellulosic feedstock comprising glucan and xylan. The feedstock is contacted with water in the presence of an acid catalyst. The resulting mixture is contacted with at least one water-immiscible organic solvent to form a mixture comprising an aqueous phase and an organic phase. Under suitable reaction conditions, furfural is produced and preferentially partitions into the organic phase, from which it may be recovered.
(FR)Selon l'invention, le furfural est produit à partir d'une matière première lignocellulosique comprenant du glucane et du xylane. Ladite matière première est mise en contact avec de l'eau en présence d'un catalyseur acide. Le mélange qui en résulte est mis en contact avec au moins un solvant organique non miscible dans l'eau de manière à former un mélange comprenant une phase aqueuse et une phase organique. Dans des conditions de réaction favorables, du furfural est produit et se sépare en phase organique, phase organique d'où il peut être extrait.
