hydrotalcite, prepared from MgO and Al2O3, acted as a highly efficient catalyst for the epoxidation of α,β-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.
由MgO和Al 2 O 3制备的碱式水滑石,作为使用过氧化氢水溶液作氧化剂对α,β-不饱和酮进行环氧化的高效催化剂。这种非均相环氧化的优点是无需有机溶剂即可高效利用H 2 O 2,后处理步骤简单,水滑石催化剂的可重复使用性。
