The term “ketones and quinones with other oxygen function” means ketones and quinones which contain also one or more of the oxygen functions referred to in previous sub‑Chapters (alcohol, ether, phenol, aldehyde, etc., functions).

(A) KETONES*

These are compounds containing the group (>C=O), so‑called “carbonyl” group, and can be represented by the general formula (R-CO-R¹), in which R and R¹stand for alkyl or aryl radicals (methyl, ethyl, propyl, phenyl, etc.).

Ketones may have two tautomeric forms, the true ketonic form (-CO-) and the enolic form (=C(OH)-), both of which fall in this heading.

(I) Acyclic ketones.

(1) Acetone (propanone) (CH₃COCH₃). Found in the products of the dry distillation of wood (methyl alcohol and crude pyroligneous acid), but is mainly obtained by synthesis. Colourless liquid with an agreeable ether‑like odour. Used in numerous organic syntheses, for the manufacture of plastics, as a solvent for acetylene, acetylcellulose and resins, etc.

(2) Butanone (methyl ethyl ketone) (CH₃COC₂H₅). Colourless liquid found in the by‑products of the distillation of alcohol from beet molasses. Also obtained by the oxidation of secondary butyl alcohol.

(3) 4‑Methylpentan‑2‑one (methyl isobutyl ketone) ((CH₃)₂CHCH₂COCH₃). Liquid with an agreeable odour; used as a solvent for cellulose nitrate, gums and resins.

(4) Mesityl oxide. Colourless liquid formed by the condensation of two acetone molecules.

(5) Phorones. Compounds formed by the condensation of three acetone molecules.

(6) Pseudoionones. Complex ketones, liquid, yellowish in colour, smelling of violets; used for the preparation of ionone (artificial violet oil).

(7) Pseudomethylionones. Liquids with the same properties as pseudoionones, with a violet‑like odour. Used in perfumery.

(8) Diacetyl (CH₃COCOCH₃)*. Greenish‑yellow liquid, with a penetrating quinone‑like odour. Used for flavouring butter and margarine.

(9) Acetylacetone (CH₃COCH₂COCH₃)*. Colourless liquid, with an agreeable odour; used in organic synthesis.

(10) Acetonylacetone (CH3COCH₂CH₂COCH₃)*. Colourless liquid with an agreeable odour; used in organic synthesis.

(II) Cyclanic, cyclenic or cycloterpenic ketones.

(1) Camphor (C₁₀H₁₆O)*. The heading covers both natural and synthetic camphor. The former is obtained from the Laurus camphora tree, indigenous to China and Japan. Synthetic camphor is derived from pinene (obtained from spirits of turpentine). Both are colourless crystalline masses, translucent, soft to the touch, and with a characteristic odour. Natural and synthetic camphor are used in medicine as an antiseptic, for the manufacture of celluloid and in moth balls.

So‑called “Borneo camphor” or “borneol” is not a ketone but an alcohol, and is formed by reducing camphor; it is excluded (heading 29.06).

(2) Cyclohexanone (C₆H₁₀O). Obtained by synthesis; a liquid with an odour similar to that of acetone. Strong solvent for acetylcellulose and natural or artificial resins.

(3) Methylcyclohexanones. Liquids insoluble in water.

(4) Ionones (C₁₃H₂₀O), formed by the condensation of citral with acetone. They include :

(a) α‑Ionone. Colourless liquid with a strong violet‑like odour.

(b) β‑Ionone. Colourless liquid with a violet‑like odour less delicate than that of α‑ionone.

Both are used in perfumery.

(5) Methylionones. Colourless to amber‑yellow liquids.

(6) Fenchone (C₁₀H₁₆O). Occurs in fennel and thuja oils. A clear, colourless liquid, with a camphor‑like odour; used as a camphor substitute.

(7) Irone. Occurs in the essential oil obtained from the roots of some varieties of iris. An oily liquid, colourless, with an iris‑like odour; strongly diluted, it has a delicate, violet‑like odour. Used in perfumery.

(8) Jasmone (C₁₁H₁₆O). Derived from jasmine‑blossom. A light yellow oil with a strong jasmine odour, used in perfumery.

(9) Carvone (C₁₀H₁₄O). Occurs in caraway, aniseed and mint oils. A colourless liquid, with a strong aromatic odour.

(10) Cyclopentanone (adipoketone) (C₄H₈CO). Occurs in the distillation products of wood. A liquid with a mint‑like odour.

(11) Menthone (C₁₀H₁₈O). Found in peppermint and other essential oils. Obtained synthetically by oxidation of menthol. An unstable, colourless, refractive liquid, with an odour of mint.

(III) Aromatic ketones.

(1) Methyl naphthyl ketone.

(2) Benzylideneacetone (C₆H₅CH=CHCOCH₃). Colourless crystals, smelling of sweet peas.

(3) Acetophenone (CH₃COC₆H₅). Oily, colourless or yellow liquid, with an agreeable aromatic odour; used in perfumery and for organic synthesis.

(4) Propiophenone.

(5) Methylacetophenone (CH₃C₆H₄COCH₃). Colourless or yellowish liquid, with an agreeable odour.

(6) Butyldimethylacetophenone.

(7) Benzophenone (C₆H₅COC₆H₅). Colourless or slightly yellow crystals with an agreeable ether‑like odour. Used in the manufacture of synthetic perfumes and for organic synthesis.

(8) Benzanthrone. Yellowish needles.

(9) Phenylacetone (phenylpropan-2-one). Colourless to light yellow liquid. Used principally in organic synthesis and as a precursor in the production of amphetamines (see the list of precursors at the end of Chapter 29).

(B) KETONE‑ALCOHOLS

Compounds whose molecules contain both the alcohol and ketone functions.

(1) 4‑Hydroxy‑4‑methylpentan‑2‑one (diacetone alcohol). Colourless liquid.

(2) Acetol (acetylcarbinol) (CH₃COCH₂OH). Colourless liquid with a penetrating odour; used as a solvent for cellulose varnishes and resins.

(C) KETONE‑ALDEHYDES

Compounds whose molecules contain both the ketone and aldehyde functions.

(D) KETONE‑PHENOLS

Compounds whose molecules contain both the ketone and phenol functions.

(E) QUINONES

These are diketones derived from aromatic compounds by conversion of two CH groups into >C=O groups with any necessary rearrangement of double bonds.

(1) Anthraquinone(C₆H₄(CO)₂C₆H₄)*. Yellow needles which, when ground, give a white powder. Used in the manufacture of dyes.

(2) p‑Benzoquinone (quinone) (C₆H₄O₂). Yellow crystals with a penetrating odour.

(F) QUINONE‑ALCOHOLS, QUINONE‑PHENOLS, QUINONE‑ALDEHYDES AND OTHER OXYGEN FUNCTION QUINONES

Quinone‑alcohols, quinone‑phenols and quinone‑aldehydes are compounds which, independently of their quinone function, also contain, in their molecules, alcohol, phenol and aldehyde functions, respectively.

(1) α‑Hydroxyanthraquinone.

(2) Quinizarin.

(3) Chrysazin.

(4) Coenzyme Q10* (ubidecarenone (INN)).

(G) HALOGENATED, SULPHONATED, NITRATED OR NITROSATED DERIVATIVES OF KETONES, QUINONES, KETONE‑ALCOHOLS, ETC., QUINONE‑ALCOHOLS, ETC.

(2) 4’‑Tert‑butyl‑2’,6’-dimethyl‑3’,5’‑dinitroacetophenone (ketone musk).

(3) Camphorsulphonic acid.

(4) Chlordecone (ISO).

* *

This heading also covers combinations of halogenated, sulphonated, nitrated or nitrosated derivatives (e.g., sulphohalogenated, nitrohalogenated, nitrosulphonated and nitrosulpho- halogenated derivatives).

Organic colouring matter is excluded from this heading (Chapter 32). The heading also excludes ketone‑bisulphite compounds which are classified as sulphonated derivatives of alcohols (headings 29.05 to 29.11).
