Title (EN) METHOD FOR PREPARING 5-HYDROXYMETHYL FURFURAL BY CONTACT CATALYSIS
(FR) PROCEDE DE PREPARATION D'HYDROXYMETHYL-5 FURFURAL PAR CATALYSE HETEROGENE
Abstract:
(EN) A method for preparing 5-hydroxymethyl furfural by contact catalysis, wherein a liquid medium containing at least one hexose, e.g. fructose, is contacted with a solid catalyst consisting of a tectosilicate or clay which is not functionalized by acid groups, e.g. a zeolite in proton form such as an H mordenite. The HMF thereby formed can be extracted using an organic solvent such as methylisobutylketone in a counter current extraction apparatus.
(FR) L'invention concerne un procédé de préparation d'hydroxyméthyl-5 furfural par catalyse hétérogène. Ce procédé consiste à mettre en contact un milieu liquide contenant au moins un hexose, par exemple du fructose avec un catalyseur solide constitué par un tectosilicate ou une argile non fonctionnalisé par des groupes acides, par exemple une zéolithe sous forme protonique telle qu'une mordénite H. On peut aussi extraire le HMF formé au moyen d'un solvant organique tel que la méthylisobutylcétone dans une installation d'extraction à contre-courant.
