| Descripción : | Nowadays, the interest in aldol condensation reactions and their products has been increased in the fine chemical industry. Aldol condensation reactions are currently carried out with homogeneous basic catalysts and their replacement by solid basic is a goal to reach. The use of solid basic
catalysts offers the advantage of decreasing corrosion and environmental problems, allowing an easier separation and recovery of the catalysts.In this way, aldol condensation reactions have been successfully carried out using MgAl hydrotalcites, zeolites and alkaline doped MgO and TiO2 catalysts. However, the catalysts obtained by the calcination of layered double hydroxides LDHs (with general formula [M1-x2+Mx3(OH)2]x+.Ax/n
n-mH2O])have become an important alternative to obtain basic catalysts, since the composition of the mixed oxides and hence
their basic properties can be tailored from the LDHs formulation.
With the purpose to develop new solid basic catalysts, in the present work, ZnAlFe LDHs
materials were prepared and calcined to obtain ZnAlFe mixed oxides. In order to study their basic properties, the materials were evaluated in the acetone gas-phase self condensation. X-ray diffraction, nitrogen adsorption and Transmission Electron Microscopy (TEM) were used for the characterization of the mixed oxides.
