Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde. It is a colorless liquid with a foul and acrid aroma. It is a colorless liquid with a foul and acrid aroma. The smell of burnt fat (as when cooking oil is heated to its smoke point ) is caused by glycerol in the burning fat breaking down into acrolein.
Acrylonitrile is an organic compound with the formula CH 2 CHCN and the structure H 2 C=CH−C≡N.It is a colorless, volatile liquid. It has a pungent odor of garlic or onions. [4] ...

Besides, 3-hydroxypropionaldehyde suffers an spontaneous dehydration in aqueous solution, and the resulting molecule is called acrolein. [3] In fact, the term reuterin is the name given to the dynamic system formed by 3-hydroxypropionaldehyde, its hydrate, the dimer, and acrolein. This last molecule, acrolein, was recently included in reuterin ...
Propionaldehyde along with acrolein has been detected in the molecular cloud Sagittarius B2 near the center of the Milky Way Galaxy, about 26,000 light years from Earth. [ 7 ] [ 8 ] [ 9 ] Measurements by the COSAC and Ptolemy instruments on comet 67/P 's surface, revealed sixteen organic compounds , four of which were seen for the first time on ...
In organic chemistry, the Michael reaction or Michael 1,4 addition is a reaction between a Michael donor (an enolate or other nucleophile) and a Michael acceptor (usually an α,β-unsaturated carbonyl) to produce a Michael adduct by creating a carbon-carbon bond at the acceptor's β-carbon.
Acrolein and malonic acid react in pyridine to give trans-2,4-pentadienoic acid with the loss of carbon dioxide. The Doebner modification of the Knoevenagel condensation entails the use of pyridine as a solvent with at least one of the withdrawing groups on the nucleophile is a carboxylic acid , for example, with malonic acid .
A route that gives better control of the product starts with acrolein, propionaldehyde, and ammonia: [1] CH 2 CHCHO + CH 3 CH 2 CHO + NH 3 → 3-CH 3 C 5 H 4 N + 2 H 2 O + H 2. It may also be obtained as a co-product of pyridine synthesis from acetaldehyde, formaldehyde, and ammonia via Chichibabin pyridine synthesis. Approximately 9,000,000 ...
