Aldol condensation reaction can be either acid catalyzed or base catalyzed. In this reaction aldehydes (or carbonyl compounds) yield aldols (or.
Aldol Condensation Base Catalyzed
An aldol condensation is a condensation reaction in organic chemistry in which an enol or an to refer to just the first (addition) stage of the process—the aldol reaction itself—as catalyzed by aldolases. However The aldol addition product can be dehydrated via two mechanisms; a strong base like potassium t-butoxide.
An aldol condensation is a condensation reaction in organic chemistry in stage of the process—the aldol reaction itself—as catalyzed by aldolases. of solvent using sodium hydroxide as the base and plus benzaldehydes.
