By oxidation with chromic acid in glacial acetic acid solution, it is converted into diphenylene ketone (C6H4)2.
A considerable body of evidence has accumulated, tending to show that some intermediate product of the nature of an aldehyde or ketone containing three carbon atoms is first formed.
When an osazone is decomposed by boiling with strong acids, the phenyl hydrazine groups break off, leaving a compound containing both an aldehyde and a ketone group.
The transition from a cellulose-ketone to the lignone-ketone involves a simple condensation without rearrangement; from which we may argue back to the greater probability of the ketonic structure of the cellulose.
Among its constituents are benzyl acetate, linalyl acetate, benzyl alcohol, indol, methyl anthranilate, and a ketone jasmone.
Ionone, a ketonefirst prepared by Tiemann, and having when diluted a pronounced violet odour.
It behaves more as a ketone than as a quinone, since with hydroxylamine it yields an oxime, and on reduction with zinc dust and caustic soda it yields a secondary alcohol, whilst it cannot be reduced by means of sulphurous acid.
A ketone of valeric acid obtained as an oily liquid.
With nitrous acid (obtained from amyl nitrite and gaseous hydrochloric acid, the ketone being dissolved in acetic acid) they form isonitrosoketones, R.
Sodium amalgam reduces them to secondary alcohols; phosphorus pentachloride replaces the carbonyl oxygen by chlorine, forming the ketone chlorides.
If the groups R and R' are identical, the ketoneis called a simple ketone, if unlike, a mixed ketone.
The ketone formula was corroborated by Nierenstein, [Footnote: Ber.
The monosaccharides are all open-chain compounds containing hydroxyl groups and either an aldehyde group or a ketone group.
Defn: A ketone of valeric acid obtained as an oily liquid.
The glucoses, or grape sugars, are ketone alcohols of the formula C6H12O6, and they turn the plane of polarization to the right or the left.
Defn: An oily liquid, obtained by distillation of calcium oleate, and probably consisting of the ketone of oleic acid.
Defn: One of a class of carbohydrates having from three to nine atoms of carbon in the molecules and having the constitution either of an aldehyde alcohol or of a ketone alcohol.
Loew considers that all substances which enter into combination with aldehyde orketone groups must be poisonous to life generally.
By the action of hydroxylamine or phenylhydrazine on aldehydes or ketones, condensation occurs between the carbonyl oxygen of the aldehyde or ketone and the amino group of the hydroxylamine or hydrazine.
The ketone group corresponds to a thermal effect of 53.
It also acts as a chromogenic centre when double bonds or ethylenic linkages are present, as in fluorene ketone or fluorenone.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "ketone" in a variety of sentences. We hope that you will now be able to make sentences using this word.
