M. Mittelbach, in Advances in Biodiesel Production, 2012. 6.4.3 Reactive distillation. Reactive distillation is a technique which combines chemical reactions and product separation in one unit. Because of the continuous removal of products formed during the reaction, the conversion limitation of equilibrium is avoided.

Aldol Condensation - Chemistry LibreTexts

Aldol Condensation - Chemistry LibreTexts

Mechanism; Condensation Types; An aldol condensation is a condensation reaction in organic chemistry in which an enol or an enolate ion reacts with a carbonyl compound to form a β-hydroxyaldehyde or β-hydroxyketone, followed by dehydration to give a conjugated enone.. Aldol condensations are important in organic synthesis, because they provide a good way to form .

Reactive distillation - Wikipedia

For example, distillation is often used to separate ethanol from water. Distillation and reflux are two lab techniques that use the same equipment to boil and condense a solution, but their purposes are different. Distillation separates components of a mixture, while reflux helps complete a reaction.

Therefore, the aldol reaction is extensively used to lengthen the molecule. The final aldol product is called β- Hydroxy carbonyl compound. If the aldol product is not isolated and placed in a base for a long time, it loses water and forms double bond through condensation, which is the reason why aldol reaction is called aldol condensation.
