aldol condensation उदाहरण वाक्य

Though primary alcohols can be oxidized under Oppenauer conditions, primary alcohols are seldom oxidized by this method due to the competing aldol condensation of aldehyde products.
The butadiene production method, which was based on aldol condensation of acetaldehyde ( 1905 ), was also implemented on industrial scale in Germany in 1936.
Butyraldehyde is converted on an industrial scale to 2-Ethylhexanol, a precursor to PVC plasticizers, by aldol condensation, followed by hydrogenation of the resulting hydroxyaldehyde.
Barium hydroxide is occasionally used in organic synthesis as a strong base, for example for the hydrolysis of esters and nitriles, and as a base in aldol condensations.
It was synthesized under the hypothesis that a polyanionic cyclization ( double Michael addition followed by aldol condensation ) would allow access to a tetracyclic intermediate with the desired functionality.

3, 4-AHBAm is made via the aminoshikimate pathway from L-Aspartate-4-semialdehyde and Dihydroxyacetone phosphate via an enzyme catalyzed aldol condensation followed by ring formation.
The initially produced aldehydes can react further by aldol condensation to either target product precursors like 2-ethylhexene-al or higher molecular weight condensation products, so-called thick oil.
Aldol condensation can occur when acetyl cyanide reacts with ( Z )-but-2-enal to form ( 2E, 4E )-hexa-2, 4-dienoyl cyanide:
The name "'aldol condensation "'is also commonly used, especially in biochemistry, to refer to just the first ( addition ) stage of the process the aldol reaction itself as catalyzed by aldolases.
When the ?, ?-unsaturated carbonyl compound is prepared in situ from two carbonyl compounds ( via an Aldol condensation ), the reaction is known as the "'Beyer method for quinolines " '.
