Aldol condensation of acetone over Mg-Al mixed oxides catalyst prepared by a citric acid route
Mg-Al mixed oxides with different Mg/Al molar ratios were prepared by using a citric acid route and tested as catalysts for the gas phase self-aldol condensation of acetone to isophorone. The sample with Mg/Al ratio of 1.0 exhibits relatively high activity and stability, and its catalytic performance could be further improved by adding alkali promoter.
