Synthesis of Sulfated Sn-Zr Mesoporous Catalysts for the Selective Dehydration of Hexose-Type Monosaccharides.

ABSTRACT: Synthesis of combined Brønsted and Lewis acid sites in SBA-15 by Zr and Sn incorporation onto the mesoporous support, followed by a sulfation procedure to get enhanced acid catalysts for fructose-to-5-hydroxymethylfurfural (HMF) selective dehydration, is here studied. Different preparation methods are used to attain the Sulfated Sn-Zr-SBA-15 material with adequate combination of Brönsted and Lewis acidity. Samples are characterized by using different analytical and spectroscopic techniques, results indicating a correlation between the preparation procedure and the acid characteristics of the materials. The latter are evaluated in the catalytic conversion of concentrated fructose solutions (30 wt%) into HMF in a biphasic system (water + iso-butylketone/2-butanol). The most efficient catalys
