The equilibrium constant is 6 × 10 −7 at room temperature, thus that the relative amount of the enol form in a sample of acetaldehyde is very small. [27] At room temperature, acetaldehyde ( CH 3 CH=O ) is more stable than vinyl alcohol ( CH 2 =CHOH ) by 42.7 kJ/mol: [ 28 ] Overall the keto-enol tautomerization occurs slowly but is catalyzed ...
Aminoacetaldehyde is the organic compound with the formula OHCCH 2 NH 2.Under the usual laboratory conditions, it is unstable, tending instead to undergo self-condensation. [1]
Phenylacetaldehyde is an aldehyde that consists of acetaldehyde bearing a phenyl substituent; the parent member of the phenylacetaldehyde class of compounds. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is an alpha-CH2-containing aldehyde and a member of ...
1,1-Diethoxyethane (acetaldehyde diethyl acetal) is a major flavoring component of distilled beverages, especially malt whisky [3] and sherry. [4] Although it is just one of many compounds containing an acetal functional group, this specific chemical is sometimes called simply acetal .
Chloral is produced commercially by the chlorination of acetaldehyde in the presence of hydrochloric acid, producing chloral hydrate. Ethanol can also be used as a feedstock. This reaction is catalyzed by antimony trichloride: H 3 CCHO + 3 Cl 2 + H 2 O → Cl 3 CCH(OH) 2 + 3 HCl. The chloral hydrate is distilled from the reaction mixture.
A tenfold dilution for each step is called a logarithmic dilution or log-dilution, a 3.16-fold (10 0.5-fold) dilution is called a half-logarithmic dilution or half-log dilution, and a 1.78-fold (10 0.25-fold) dilution is called a quarter-logarithmic dilution or quarter-log dilution.
Acetaldehyde ammonia trimer is a chemical compound described by the formula (CH 3 CHNH) 3. The pure material is colourless but samples often appear light yellow or slightly beige due to the degradation by oxidation.
