log 10 of Acetaldehyde vapor pressure. Uses formula: log e P m m H g = {\displaystyle \scriptstyle \log _{e}P_{mmHg}=} log e ( 760 101.325 ) − 18.27131 log e ( T + 273.15 ) − 7241.251 T + 273.15 + 130.8048 + 2.633634 × 10 − 5 ( T + 273.15 ) 2 {\displaystyle \scriptstyle \log _{e}({\frac {760}{101.325}})-18.27131\log _{e}(T+ ...
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 ...
Ethylene vinyl alcohol (EVOH) is a formal copolymer of ethylene and vinyl alcohol.Because the latter monomer mainly exists as its tautomer acetaldehyde, the copolymer is prepared by polymerization of ethylene and vinyl acetate to give the ethylene vinyl acetate (EVA) copolymer followed by hydrolysis.
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 ...
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]

Serial dilution is one of the core foundational practices of homeopathy, with "succussion", or shaking, occurring between each dilution.In homeopathy, serial dilutions (called potentisation) are often taken so far that by the time the last dilution is completed, no molecules of the original substance are likely to remain.
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.
