Phenol
(gcide) | Phenol \Phe"nol\ (f[=e]"n[=o]l; 277), n. [Gr. fai`nein to show +
-ol: cf. F. ph['e]nol.] (Chem.)
1. A white or pinkish crystalline substance, C6H5OH,
produced by the destructive distillation of many organic
bodies, as wood, coal, etc., and obtained from the heavy
oil from coal tar.
[1913 Webster]
Note: It has a peculiar odor, somewhat resembling creosote,
which is a complex mixture of phenol derivatives. It is
of the type of alcohols, and is called also {phenyl
alcohol}, but has acid properties, and hence is
popularly called carbolic acid, and was formerly
called phenic acid. It is a powerful caustic poison,
and in dilute solution has been used as an antiseptic.
[1913 Webster]
2. Any one of the series of hydroxyl derivatives of which
phenol proper is the type.
[1913 Webster]
Glacial phenol (Chem.), pure crystallized phenol or
carbolic acid.
Phenol acid (Chem.), any one of a series of compounds which
are at once a derivative of phenol and an organic acid;
thus, salicylic acid is a phenol acid.
Phenol alcohol (Chem.), any one of series of derivatives of
phenol and carbinol which have the properties of both
combined; thus, saligenin is a phenol alcohol.
Phenol aldehyde (Chem.), any one of a series of compounds
having both phenol and aldehyde properties.
Phenol phthalein. See phenolphthalein.
