Three different methods of epoxidation using heterogeneous catalysts are compared, under different conditions, in the benchmark epoxidation of α-isophorone. The use of tert-butyl hydroperoxide/KF-Al₂O₃ in toluene leads to the highest (almost quantitative) yield, whereas the system H₂O₂/hydrotalcite leads to the best result described to date using this oxidant.
