Inside Back Cover: Direct Hydrogenation of Biomass-Derived Butyric Acid to n-Butanol over a Ruthenium-Tin Bimetallic Catalyst (ChemSusChem 11/2014).

The Back Inside Cover picture shows an important method for the production of bioalcohols. The method relies on a hybrid conversion process that is based on the combination of selective hydrogenation of bio‐based organic carboxylic acids with the fermentation of biomass to the corresponding acids. A powerful strategy would be the use of direct hydrogenation of organic carboxylic acids without having to use additional esterification processes. To achieve this powerful strategy, it is necessary to adopt effective hydrogenation catalysts to produce yields of bioalcohols above 95% without deactivation of the catalyst. More details on this strategy can be found in the Communication by Jong‐San Chang on page 2998 (DOI: 10.1002/cssc.201402311). [ABSTRACT FROM AUTHOR]
