2_02/2009Cover Picture: Stable Hybrid Silica Nanosieve Membranes for the Dehydration of Lower Alcohols (ChemSusChem 2/2009)

The cover picture shows the membrane separation of water (blue arrow) from crude ethanol (red arrows) as a key enabling technology in the production of ethanol from lignocellulosic biomass. This technology is generally considered to be one of the more viable options for the transition to a sustainable transportation fuel supply. In their Communication on page 158, J. F. Vente and co-workers describe the preparation and performance of an amorphous bridged silsesquioxane-based membrane characterized by Si–CH2–Si building units. This new organic–inorganic hybrid silica membrane allows the dehydration of ethanol and, to some extent, methanol. Even the presence of 1.5 wt % acetic acid does not affect the separation performance of these membranes.
