(gcide) | oenanthic \oe*nan"thic\, a. [Gr. ? the first shoot of the vine,
the vine blossom, the vine; o'i`nh the vine + ? bloom,
'a`nqos flower.] (Chem.)
Having, or imparting, the odor characteristic of the bouquet
of wine; specifically used, formerly, to designate an acid
(oenanthic acid) whose ethereal salts were supposed to
occasion the peculiar bouquet, or aroma, of old wine. Cf.
oenanthylic.
[1913 Webster]
oenanthic acid, oenanthic acid (Chem.), an acid
(C6H13.CO.OH) obtained from [oe]nanthic ether by the
action of alkalies; called also n-heptanoic acid,
1-heptanecarboxylic acid, enanthic acid, {enanthylic
acid} and oenanthylic acid. It has the odor of sour
sweat. It has the CAS registry number 111-14-8.
oenanthic ether, an ethereal substance (not to be confused
with the bouquet, or aroma, of wine) found in wine lees,
and consisting of a complex mixture of the ethereal salts
of several of the higher acids of the acetic acid series.
It has an ethereal odor, and it used in flavoring
artificial wines and liquors. Called also oil of wine.

carboxylic acid
(gcide) | carboxylic acid \carboxylic acid\ n. (Chem.)
an organic compound whose acidity is due to the presence of a
carboxyl gorup. Monocarboxylic acids (such as acetic acid
or butyric acid) have one carboxyl group, dicarboxylic acids
(such as oxalic acid or malonic acid) have two, tricarboxylic
acids (such as citric acid) have three.
[PJC] |
carboxylic group
(gcide) | carboxyl group \car*box"yl group`\ (k[aum]r*b[o^]ks"[i^]l
gr[=oo]p), n. (Chem.)
a monovalent organic radical (written -COOH, -CO2H or
-CO.OH) whose presence confers acidic properties on the
compound containing it; -- called also carboxylic group.
Monocarboxylic acids (such as acetic acid or butyric acid)
have one carboxyl group, dicarboxylic acids (such as oxalic
acid or malonic acid) have two, tricarboxylic acids (such as
citric acid) have three. It is weakly acidic, the pKa of
acetic acid being 4.75.
[PJC] |
dicarboxylic
(gcide) | dicarbonic \di`car*bon"ic\ (d[imac]`k[aum]r*b[o^]n"[i^]k), a.
[Pref. di- + carbonic.] (Chem.)
Containing two carbon residues, or two carboxyl groups or
radicals; as, oxalic acid is the simplest dicarbonic acid. In
the latter sense, synonymous with dicarboxylic; as,
succinic acid is a dicarboxylic acid.
[1913 Webster +PJC] |
monocarboxylic
(gcide) | monocarbonic \mon`o*car*bon"ic\, monocarboxylic
\mon`o*car*box*yl"ic\, a. [Mono- + carbonic.] (Chem.)
Containing one carboxyl group; as, acetic acid is a
monocarbonic acid. The more common term is monocarboxylic.
Contrasted with dicarboxylic, tricarboxylic, etc.

propylene dicarboxylic acid
(gcide) | itaconic acid \it`a*con"ic ac"id\, n. (Chem.)
