Aldol Synthesis of Dibenzalacetone

The goal of this experiment was to compound dibenzalacet ane by aldol synthesis. The call down ?aldehyde-alcohol synthesis? was taken from the linguistic communication ?aldehyde and alcohol?. This is because the return of this solution contains both an aldehyde and alcohol. The carbon-carbon bond-forming fight backion is referred to as aldol addition. An aldol condensate dampens many species of products if the reactant is more than one. Therefore, the aldehyde has to react with itself to yield one product. part: Followed according to the lab manual.

Acetone is keep back as the enolate forming compound, adding to the benzaldehyde followed by the drying up to form a benzal group. As for the low yield (40.78%), it lowlife be attri howevered to a few 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 reception would not go to utmost and less yield corporation be expected.

It might be ca utilize by the solvent utilize during recrystallization was a little touch more than advised in the lab manual (~15 mL instead of ~12 mL of ethanol). The crystal, (I?m fearful 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 except for a trough at 3052.68 cm-1 that...
