Aldol Synthesis of Dibenzalacetone

The goal of this experiment was to synthesise dibenzalacet ane by aldehyde-alcohol synthesis. The call down ?aldehyde-alcohol synthesis? was taken from the delivery ?aldehyde and alcohol?. This is because the return of this reception contains both an aldehyde and alcohol. The carbon-carbon bond-forming respondion is referred to as aldol addition. An aldol space capsule restorations many species of products if the reactant is more than one. Therefore, the aldehyde has to react with itself to yield one product. military operation: Followed according to the lab manual.

Acetone is follow through as the enolate forming compound, adding to the benzaldehyde followed by the desiccation to form a benzal group. As for the low yield (40.78%), it rear end be attri saveed to a fewer factors. The first being that this reply goes by an equilibrium and that if this was not shifted far enough to the dibenzalacetone side, the chemical reaction would not go to shutting and less yield burn be expected.

It might be ca utilise by the solvent utilise during recrystallization was a little present moment more than advised in the lab manual (~15 mL instead of ~12 mL of ethanol). The crystal, (I?m apprehensive if) it would be solved beyond recrystallizing at this point; but it recrystallized as it cools down, so I was sure that the solvent employ was not too much. The crystal was also wasted in the Erlenmeyer flask and some on the filter paper used to dry it. IR analysisThe IR result from this experiment shows no significant stretches infrequency higher(prenominal) than 2000 cm-1 pull for a trough at 3052.68 cm-1 that...
