Interaction between Sn(n-C//4H//9)//4 and Rh/SiO//2 catalyst results in a new kind of catalyst which is both more active and more selective than Rh/SiO//2 for the hydrogenation of ethyl acetate to ethanol. Depending on the reaction conditions, conversions as high as 100% and selectivities as high as 98% can be reached at 250 degree C under 50 atm of hydrogen. The comparison between the chemisorption properties of Rh/SiO//2 with those of Rh-Sn/SiO//2 indicates that there is an inverse relationship between the amount of tin fixed (probably on rhodium) and the amount of hydrogen 'weakly' adsorbed on rhodium. Conversely, there is a linear relationship between the amount of tin fixed and the amount of strongly adsorbed hydrogen.
