摘要：
The layered double hydroxides-supported diisopropylamide (LDH-DA) catalyst is found to be an efficient and selective solid base for aldol, Knoevenagel, Henry, Michael, transesterification and epoxidation reactions under liquid phase conditions. LDH-DA is synthesized by the interaction of lithium diisopropylamide with LDH-NO3 (as-synthesized) and calcined LDH-NO3. The LDH-DA (Mg/Al, 3/1) and their precursors are well characterized by using various instrumental techniques such as FT-IR, TGA and DTA, powder XRD, solid state Al-27 MAS NMR spectroscopy, SEM and XPS (ESCA).
