Heterogeneous Acid-Base Catalyzed Aldol Condensation: Acetaldehyde and Heptaldehyde on Hydrotalcites. Optimization of Operatory Conditions

The aldol condensation between acetaldehyde and heptaldehyde, aiming the cross-condensation as a way to increase the length of the linear carbon chain, was investigated in heterogeneous system, using the commercial hydrotalcite KW2200 as catalyst. A parametric study allowing to find the optimal operatory conditions was performed. The yield values towards the target compound were around 25%, suggesting to continue the work and synthesize new more performant catalysts for this purpose.
