Chemisorption of mixtures of propylene and oxygen on an oxide antimony-tin catalyst and tin dioxide

1. The individual, successive, and simultaneous chemisorption of propylene and oxygen on a catalyst of mild oxidation of hydrocarbons (Sn/Sb) and a catalyst of profound oxidation (SnO2) was studied. 2. At temperatures substantially below the temperature of catalysis, C3H6 and O2 are adsorbed reversibly on both catalysts. 3. Under the conditions of precatalysis, the chemisorption of propylene and oxygen on Sn/Sb and...
