Preparation of Mg-doped Ce-Zr Solid Catalysts and Their Catalytic Potency for the Synthesis of 5-Arylidene-2,4-Thiazolidinediones via Knoevenagel Condensation

摘要: A series of Mg-doped Ce-Zr mixed oxides with different molar ratios were prepared by a simple co-precipitation method. The surface characterization these materials investigated means XRD, FT-IR, SEM-EDS, CO2-TPD and BET techniques. catalytic activity the was tested synthesizing 5-arylidene-2,4-thiazolidinedione derivatives via Knoevenagel condensation using aromatic aldehydes 2,4-thiazolidinedione in ethanol:water medium. best obtained Ce1Mg0.6Zr0.4O2. particle size or crystallite estimated Debye-Scherrer equation. Addition MgO to metal affected both activity.
