P. Kluson et L. Cerveny, RU-SN CATALYST - A NEW PROMISING SYSTEM FOR SELECTIVE HYDROGENATION OF A CARBONYL GROUP, Chemicke listy, 91(2), 1997, pp. 100-104
Unsaturated alcohols are prepared by selective hydrogenation of unsatu
rated aldehydes, ketones, acids, and their esters. Special attention i
s paid to the Ru-Sn catalytic systems suitable for such reactions. The
Ru-Sn catalyst is usually prepared by co-impregnation, sol-gel method
, or so called surface controlled reaction. Interesting topics and spe
cific features regarding this catalyst system are discussed. Role of S
n and its promotion effect on Ru catalytic properties are explained in
a separate chapter. These properties are documented on several practi
cal examples (e.g., selective hydrogenation of cinnamaldehyde, crotona
ldehyde, oleic acid, etc.).
