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


Isophorone is used as a solvent for vinylresins and cellulose esters, and in pesticides.


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.

Health Hazard

Isophorone is an irritant, moderately toxic athigh concentrations, mutagenic and possiblycarcinogenic. Inhalation of its vapors cancause mild irritation of the eyes, nose, andthroat. Exposure to 840 ppm for 4 hours resulted in severe eye irritation in guineapigs. Its irritation effect on human eyes maybe felt at 25–40 ppm. At concentrationsabove 200 ppm, it may cause irritation ofthe throat, headache, nausea, dizziness, and afeeling of suffocation (ACGIH 1986). In rats,exposure to 1840 ppm for 4 hours was fatal.Ingestion of isophorone can cause narcosis,dermatitis, headache, and dizziness.
LD50 value, oral (rats): 2330 mg/kg
Isophorone is mutagenic and when fed torats orally, 258 g/kg for 2 years, it causedkidney tumor. Its carcinogenicity on humansis not reported.

Fire Hazard


Fire Hazard

Flash Point (°F): 205 ℃, 184 ℃; Flammable Limits in Air (%): 0.84-3.8; Fire Extinguishing Agents: Dry chemical, foam, or carbon dioxide; Fire Extinguishing Agents Not To Be Used: Water may be ineffective; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 864; Electrical Hazard: No data; Burning Rate: 4.0 mm/min.

Chemical Reactivity

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Industrial uses

Isophorone is an excellent solvent for cellulose esters, nitrocellulose, natural and synthetic resins. Isophorone has a very high aromatic hydrocarbon dilution ratio in nitrocellulose formulations: 5.7 for toluene and 5.1 for xylene. The excellent solvency of isophorone allows the preparation of 45% solids nitrocellulose solutions at room temperatures.

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.]
