Invited for this month′s cover is the Catalysis Center for Energy Innovation at the University of Delaware. The image shows the synergy of first principles calculations with vibrational spectroscopy to elucidate the stability of 5-hydroxymethylfurfural (HMF) in DMSO/water mixtures. The Full Paper itself is available on page 117 (10.1002/cssc.201300786).

12345Hexose dehydration to 5-hydroxymethylfurfural (HMF) is a key reaction for converting carbohydrates to fuels and chemicals, hampered by the low yields due to HMF degradation. It is well known that the utilization of some organic co-solvents, like DMSO, staves off undesired reactions. Elucidating the role of co-solvent in HMF stability contributes to the fundamental understanding of the chemistry and sets the foundations for rational solvent selection.

This study reveals the first experimental evidence of competitive and selective solvation of HMF carbonyl group by an aprotic solvent in the presence of water. This finding, in conjunction with the calculated effect of DMSO on HMF LUMO energy, can explain the enhanced stability of HMF toward degradation reactions when some organic co-solvents are used.
