TL;DR: In this paper, the authors investigated the selectivity of fructose to 5-hydroxymethylfurfural in a batch mode in the presence of a series of dealuminated H-form mordenites as catalysts, at 165°C, and in a solvent mixture consisting of water and methyl isobutyl ketone.

TL;DR: In this article, the authors used H-mordenite and mordenites as catalysts for the formation of furfural from xylose in a batch mode at 170°C and in a solvent mixture consisting of water and toluene.

TL;DR: In this paper, a new solid-liquid-liquid reactor has been developed in order to simultaneously benefit from the advantages of both the catalytic activity and molecular sieve properties of zeolites, the superior performances of concentration gradient reactors for positive order consecutive chemical reactions and the extraction of an intermediate target product by a solvent with countercurrent flows.

TL;DR: In this paper, the advantages of the use of microporous catalysis like zeolites compared to macroporous catalytic systems, like ion exchange resin, to achieve the selective transformation of fructrose or fructose precursors sucrose or inulin into 5-hydroxymethylfurfural in water as the solvent were reported.

TL;DR: In this paper, a method for preparing 5-hydroxymethyl furfural by contact catalysis was proposed, where 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.
