Isophorone is the name of a chemical compound, a colorless to yellow liquid with a characteristic odor, which is used as a solvent and as a synthesis intermediate. Isophorone should also occur naturally in cranberries. Although direct contact with isophorone causes irritation, there is no convincing evidence for the toxicity of the substance in continuous use.

History

Isophorone was first marketed in 1967 as a possible acetone product of the former Degussa and his sales secured their location in Herne.

Extraction

Isophorone can be produced by the catalyzed self-condensation of acetone.

Use

Isophorone is used as a solvent in paint, ink and adhesive industries. In the synthesis, it is used mainly for the preparation of isophorone diamine, isophorone diisocyanate and 3,5-dimethylphenol. Isophorone is part of colored indicators with positive solvatochromism ( LSG Brooker and Ralf E. Lemke ) and the negative solvatochromic anions with positive thermochromism (Ralf E. Lemke ).
