Condensation of Acetone to Diacetone Alcohol over Structured MgO/Al2O3-Al Catalyst Packing
A novel solid base catalyst, structured MgO/Al2O3-Al catalyst packing, was prepared by supporting MgO onto a thin film of alumina that was formed by anodic oxidation of high purity aluminium foils. Some preparation parameters including the molar ratio of Mg(NO3)2•6H2O to CH3(CH2)16COOH, the aging time, the calcination temperature and time were investigated by using the catalyst for the condensation of acetone to diacetone alcohol. Each of those factors had some influence on the catalyst activity and an optimum value was obtained. The conversion of acetone was 20.2%, and the selectivity to diacetone alcohol was 100% under the optimized preparation conditions.
