- Ketone Ke"tone (k[=e]"t[=o]n), n. [Cf. {Acetone}.] (Chem.)
One of a large class of organic substances resembling the
aldehydes, obtained by the distillation of certain salts of
organic acids and consisting of carbonyl ({CO}) united with
two hydrocarbon radicals. In general the ketones are
colorless volatile liquids having a pungent ethereal odor.
[1913 Webster]
Note: The ketones are named by adding the suffix-one to the stems of the organic acids from which they are respectively derived; thus, acetic acid gives acetone; butyric acid, butyrone, etc. [1913 Webster]
