CRINOLINE OR QUINOLINE.
Formula.—CgH^N.
Derivation.—Chinoline was first obtained from coal tar, but
afterward- from the cinchona alkaloids. More recently it has
been produced by the action of glycerin on aniline, or nitro-ben-
zol. It is an oily liquid, with highly refracting property, and it
combines with acids to form salts. The salt. Tartrate of Chino-
line., is not so deliquescent as the other salts formed by its com-
bination with acids, and is in the form of lustrous crystals, which
preserve their form even in a damp atmosphere, although they
are soluble in water. Chinoline is very soluble in alcohol, and
sparingly soluble in water.
Medical Properties and Action.—Chinoline, like other phenol
derivatives, such as resorcin, hydroquinone, etc., possesses the
power to lower fever heat, but does not affect the normal tem-
perature.
Therapeutic Uses.—Like resorcin, chinoline has been used in
intermittent and remittent fevers with great success ; also in sep-
tic disorders. Topically, chinoline is a valuable antiseptic, and
successfully acts upon minute organisms, preventing their increase
and septic decomposition. A five per cent, solution of the tar-
trate of chinoline, the salt generally employed, has been applied
locally in diphtheria, with marked effect.
Dose.—Of chinoline, gr. v to xv.
Dental Uses.—Chinoline is used in dental practice as an anti-
septic, belonging to the same class as resorcin, the salt tartrate of
chinolin, in the form of a five per cent, solution, being preferable
for local application. It is also used in combination with car-
bolic acid, for application on cotton to an aching cavity from
which a tooth has been extracted.
