Title
(EN) RECOVERY OF SUGARS FROM IONIC LIQUID BIOMASS LIQUOR BY SOLVENT EXTRACTION
(FR) RÉCUPÉRATION DE GLUCIDES À PARTIR DE LIQUEUR DE BIOMASSE LIQUIDE IONIQUE PAR EXTRACTION DANS UN SOLVANT
Abstract
(EN)
The present invention provides for a composition comprising a solution comprising (a) an ionic liquid (IL) or ionic liquid-aqueous (ILA) phase and (b) an organic phase, wherein the solution comprises a sugar and a boronic acid. The present invention also provides for a method of removing a sugar from a solution, comprising: (a) providing a solution comprising (i) an IL or ILA phase and (ii) an organic phase, wherein the solution comprises an IL, a sugar and a boronic acid; (b) contacting the sugar with the boronic acid to form a sugar- boronic acid complex, (c) separating the organic phase and the aqueous phase, wherein the organic phase contains the sugar-boronic acid complex, and optionally (d) separating the sugar from the organic phase.
(FR)
La présente invention concerne une composition comprenant une solution comprenant (a) une phase liquide ionique (IL) ou liquide ionique-aqueuse (ILA) et (b) une phase organique, où la solution comprend un glucide et un acide borique. La présente invention concerne en outre un procédé d'élimination d'un glucide d'une solution, comprenant : (a) la production d'une solution comprenant (i) une phase IL ou ILA et (ii) une phase organique, où la solution comprend un IL, un glucide et un acide borique ; (b) la mise en contact du glucide avec l'acide borique pour former un complexe glucide-acide borique, (c) la séparation de la phase organique et la phase aqueuse, où la phase organique contient le complexe glucide-acide borique, et facultativement (d) la séparation du glucide de la phase organique.
