Acetophenone Benzaldehyde Aldol Condensation

Acetophenone Benzaldehyde Aldol Condensation. Each chalcone is then isolated by suction filtration after washing with water. The reaction in which benzaldehyde reacts with acetophenone in presence of sodium hydroxide solution is known as cross aldol condensation reaction in which benzaldehyde which is aromatic aldehyde compound reacts with acetophenone which aliphatic alkyl ketone and sodium hydroxide acts as an catalyst here.

The ketone reactions are also called aldol reactions due to their similarity with the aldehydes. The aldol condensation is a reaction that is named based on the type of product formed when two aldehydes (or ketones), in the presence of dilute base, yields a molecule having both alcohol and aldehyde functional groups.
