Webster's Revised Unabridged Dictionary
    • n Ketone kē"tōn (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.☞ 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.

Century Dictionary and Cyclopedia
    • n ketone A compound in which the carbonyl group CO unites two alcohol radicals: as, methyl-ethyl ketone, CH3.CO.C2H5. The ketones are volatile ethereal liquids allied to the aldehydes, but differing from them in that they do not reduce ammoniacal silver solutions, are converted into secondary alcohols by nascent hydrogen, and by further oxidation are decomposed. The ketones are also called acetones, but this term should be reserved for dimethyl ketone.
