Experiment 15 Preparation of Dibenzalacetone

Experiment 15 Preparation of Dibenzalacetone In this experiment we will prepare dibenzalacetone from acetone and two equivalents of benzaldehyde under basic conditions This is an example of a crossed-aldol (or mixed-aldol) reaction The overall reaction is shown in Figure 15 1 and a detailed mechanism is given in Figure 15 2

How many G acetone x 1 mol dibenzalacetone?
Theoretical Yield: 0 g Acetone x 1 mol Acetone x 1 mol Dibenzalacetone x 234 g Dibenzalacetone = 0 g 58 g Acetone 1 mol Acetone 1 mol Dibenzalacetone The melting point of recrystallized product differed from found literature value, indicating presence of impurities. This can be seen in Table 1.
What is dibenzalacetone by a Claisen-Schmidt reaction?
Dibenzalacetone by the aldol condensation. Purpose: Synthesize dibenzalacetone which is aldol compound by Claisen-Schmidt reaction to prove that reaction of an acetone with aldehyde, catalyzed by a strong base, yields an aldehyde + alcohol mixed compound known as (aldol).
How do you make dibenzalacetone a solid?
Place a septum and cap on the vial and commence stirring. Remove the cap and add 0.5 mL of 10% aqueous NaOH over a period of 5 min with stirring. Once NaOH addition is complete, cap the vial and allow it to stir rapidly for 25 min. Dibenzalacetone will crash out of the solution as a solid during the course of the reaction.
