PARACONINE n.
base resembling and isomeric with conine, and obtained as a colorless liquid from butyric aldehyde and ammonia.

PRIMARY a.
alcohol which possess the group CH2.OH, and can be oxidized so as to form a corresponding aldehyde and acid having the same number of carbon atoms; -- distinguished from secondary and tertiary alcohols. -- Primary amine (Chem.), an amine containing the amido group, or a derivative of ammonia in which only one atom of…
QUINALDINE n.
liquid of a slightly pungent odor, C9H6N.CH3, first obtained as a condensation product of aldehyde and aniline, and regarded as a derivative of quinoline; -- called also methyl quinoline. [Written also chinaldine.]

signating, an acid, C4H7N3O2, obtained, by the action of the vapor of cyanic acid on cold aldehyde, as a white crystalline substance having a slightly acid taste and faint smell; -- called also ethidene- or ethylidene-biuret.
UNSATURATED a.
, certain other elements or compounds, without the elimination of any side product; thus, aldehyde, ethylene, and ammonia are unsaturated.
VALERIDINE n.
A base, C10H19N, produced by heating valeric aldehyde with ammonia. It is probably related to the conine alkaloids.
VANILLIC a.
fically, designating an alcohol and an acid respectively, vanillin being the intermediate aldehyde.
VANILLIN n.
A white crystalline aldehyde having a burning taste and characteristic odor of vanilla. It is extracted from vanilla pods, and is also obtained by the decomposition of coniferin, and by the oxidation of eugenol.
