Title: Synthesis of a Benzalacetophenone: A mixed Aldol Condensation reaction

Introduction: Aldol Condensation is an extremely useful carbon-carbon bond-forming reaction in organic chemistry. Aldol reactions are formed when two molecules of the same aldehyde or ketone react in the presence of a base. The end result of this reaction is a β-hydroxy carbonyl compound. The β-hydroxy aldehyde and β-hydroxy ketone are easily dehydrated because the double bond formed is in conjunction with the carbonyl group. Conjunction increases the stability of the conjugated product.

The objective of the experiment is to observe the synthesis of benzalactohnone.

Abstract: A flask with a magnetic stirring rod was obtained and placed on a magnetic stirrer. Then 0.02 mole of p-dimethylaminobenzaldehyde and 1 mole of acetophenone was placed in 10 ml of 95% ethanol and set to be dissolved. One dissolve 5 ml of sodium hydroxide was added. The mixture was then stirred for at least 30 minutes. Once mixture was completely dissolved, 50 ml of ice cold water was added and then placed in an ice bath for at least 5 minutes. A colored precipitate was then formed, and then obtained through vacuum filtration.
