Abstract
Acetylation of diisobutylene and diisoamylene to form methyl ketones was carried out with acetic anhydride in the presence of cation exchange resin (Amberlyst-15) and acid-treated clay (Engelhard, F-24) as catalysts in the temperature range of 50-100°C. The effect of catalyst loading, temperature and mole ratio of olefin to acetic anhydride was studied. The overall rate of reaction increased with an increase in the catalyst loading, temperature and mole ratio of acetic anhydride to olefin. The kinetic data were analyzed using a heterogeneous model based on Rideal-Eley rate expressions. The values of apparent rate constants and activation energy are reported.
