coal-tar creosote (encz) | coal-tar creosote, n: |
Coal-tar creosote (gcide) | Creosote \Cre"o*sote\ (kr[=e]"[-o]*s[=o]t), n. [Gr. kre`as, gen.
kre`ws, flesh + sw`zein to preserve.] (Chem.)
Wood-tar oil; an oily antiseptic liquid, of a burning smoky
taste, colorless when pure, but usually colored yellow or
brown by impurity or exposure. It is a complex mixture of
various phenols and their ethers, and is obtained by the
distillation of wood tar, especially that of beechwood.
[1913 Webster]
Note: It is remarkable as an antiseptic and deodorizer in the
preservation of wood, flesh, etc., and in the
prevention of putrefaction; but it is a poor germicide,
and in this respect has been overrated. Smoked meat, as
ham, owes its preservation and taste to a small
quantity of creosote absorbed from the smoke to which
it is exposed. Carbolic acid is phenol[1] proper,
while creosote is a mixture of several phenols.
[1913 Webster]
Coal-tar creosote (Chem.), a colorless or yellow, oily
liquid, obtained in the distillation of coal tar, and
resembling wood-tar oil, or creosote proper, in
composition and properties.
