摘要：

The base hydrotalcite, prepared from MgO and Al2O3, acted as a highly efficient catalyst for the epoxidation of alpha,beta-unsaturated ketones using aqueous hydrogen peroxide as an oxidant. This heterogeneous epoxidation has the advantages of a high efficiency of H2O2 utilization Without organic solvents, a simple workup procedure, and reusability of the hydrotalcite catalyst.
