Isophorone Chemical Properties,Uses,Production


Isophorone (chemical formula: C9H14O) has its full name being 3, 5, 5-Trimethyl-2-cyclohexen-1-one. It is a kind of α, β-unsaturated cyclic ketone, and is a flavoring ingredient existing in cranberries and saffron. Isophorone can be used as a solvent in some printing inks, paints, lacquers, adhesives, copolymers, coatings, finishings and pesticide. It can also act as an intermediate in organic synthesis as well as the ingredient in wood preservatives and floor sealants. It is mainly manufactured through the self-condensation of acetone with KOH.


Chemical Properties

light yellow liquid


ChEBI: A cyclic ketone, the structure of which is that of cyclohex-2-en-1-one substituted by methyl groups at positions 3, 5 and 5.


Solvent in some printing inks, paints, lacquers and adhesives.

General Description

A clear colorless liquid, with a camphor-like odor. Less dense than water and insoluble in water. Boiling point 420°F. Flash point near 200°F. Contact irritates skin and eyes. Toxic by ingestion. Used as a solvent and in pesticides.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Ketones, such as Isophorone, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. Forms explosive peroxides


Irritant to skin and eyes. Possible carcinogen.

Health Hazard

LIQUID: Irritating to skin and eyes. Harmful if swallowed.

Fire Hazard


Purification Methods

Wash isophorone with aqueous 5% Na2CO3 and then distil it under reduced pressure immediately before use. Alternatively, it can be purified via the semicarbazone. [Erskine & Waight J Chem Soc 3425 1960, Beilstein 7 IV 165.]
