aldol condensation lab report abstract

RESULTS. Selective C–C coupling of oxygenates via aldol condensation has the potential to produce useful chemicals from aldehydes and ketones. This molecule contains two Alpha-Carbons (Carbon that present nearby to functional group attached carbon) so here any of the Alpha-Hydrogen can abstracted. Several layered double hydroxides (with Mg:Al ratio varying from 2:1 to 4:1) were prepared by a co‐precipitation method at constant pH value. Although aldol condensation is one of the most important organic reactions, capable of forming new C–C bonds, its mechanism has never been fully established. We now conclude that the rate-limiting step in the base-catalyzed aldol condensation of benzaldehydes with acetophenones, to produce chalcones, is the final loss of hydroxide and formation of the C═C bond. By employing a stepwise sequence, you will be able to isolate the mono-addition (Product A), and repeat the reaction, this time using (Product A) as the source ketone to form the bis-addition (Product B). The melting point for Dibenzalacetone is 110 o C and the experiemtnal melting point was close to 105 o C. Although the melting points are not the same, they are very close.
