acetaldehyde
n 1: a colorless volatile water-soluble liquid aldehyde used
chiefly in the manufacture of acetic acid and perfumes and
drugs [synonym: {acetaldehyde}, {ethanal}]

Acetaldehyde \Ac`et*al"de*hyde\, n.
Acetic aldehyde. See {Aldehyde}.
[1913 Webster]


Aldehyde \Al"de*hyde\ ([a^]l"d[-e]*h[imac]d), n. [Abbrev. fr.
alcohol dehydrogenatum, alcohol deprived of its hydrogen.]
1. (Chem.) A colorless, mobile, and very volatile liquid
obtained from alcohol by certain processes of oxidation.
[1913 Webster]

2. (Chem.) Any compound having the group {-CHO}. Methyl
aldehyde, the simplest aldehyde, is more commonly called
formaldehyde, {H-CHO}, and acetic aldehyde is now more
commonly called {acetaldehyde}. The higher aldehydes may
be solids. A {reducing sugar} typically contains the
aldehyde group.
[PJC]

Note: The aldehydes are intermediate between the alcohols and
acids, and differ from the alcohols in having two less
hydrogen atoms in the molecule, as common aldehyde
(called also {acetaldehyde}, {acetic aldehyde} or
{ethyl aldehyde}), {C2H4O}; methyl aldehyde (called
also {formaldehyde}), {CH2O}.
[1913 Webster PJC]

{Aldehyde ammonia} (Chem.), a compound formed by the union of
aldehyde with ammonia.
[1913 Webster]
