Outline of Final Research Achievements

Base strength of solid base was evaluated by applying a temperature-programmed desorption using hydrocarbons (propane, propylene, isobutene, and isobutene). Adsorption of hydrocarbons on CaO, which was activated by heating at 773 K for 2h, was performed at 143 K, and temperature increasing rate was 1 K/min in He stream. Peak temperatures of each hydrocarbons were 172 K, 193 K, 206 K, and 228 K for propane, propylene, isobutene, and isobutene, respectively. This result indicates that these was an acid-base like interaction between hydrocarbons and base sites. The strength of this acid-base like interaction was evaluated as an activation energy of desorption of propylene.
