Abstract[English]
The invention relates to a method for treating a mixture M in the aqueous phase of compounds comprising C5 sugars with 5 carbons and C6 sugars with 6 carbons, said C5 sugars and/or said C6 sugars being partly in monomeric form and partly in oligomeric form, such that said mixture is heated, in the presence of acid(s), at a temperature T of at least 60°C so as to obtain a mixture M' enriched in C5 sugars in monomeric form and/or in C6 sugars in monomeric form and depleted in C5 sugars in oligomeric form and/or in C6 sugars in oligomeric form.[French]
L'invention concerne un procédé de traitement d'un mélange M en phase aqueuse de composés comprenant des sucres C5 avec 5 carbones et des sucres C6 avec 6 carbones, lesdits sucres C5 et/ou lesdits sucres C6 étant pour partie sous forme monomérique et pour partie sous forme oligomérique, tel qu'on chauffe ledit mélange, en présence d'acide(s), à une température T d'au moins 60°C afin d'obtenir un mélange M' enrichi en sucres C5 sous forme monomérique et/ou en sucres C6 sous forme monomérique et appauvri en sucres C5 forme oligomérique et/ou en sucres C6 sous forme oligomériquefigure pour l'abrégé :
