Description and Uses

Isophorone is used as a solvent for vinylresins and cellulose esters, and in pesticides. solvent in some printing inks, paints, lacquers and adhesives. As a cyclic unsaturated ketone, isophorone can be aromatized to 3,5-dimethylphenol or 2,3,5-trimethylphenol. Hydrogenation leads, depending on conditions, to 3,3,5-trimethylcyclohexanone or 3,3,5- trimethylcyclohexanol, from which trimethyladipic acid is obtained by oxidation [78]. Trimethyladipic acid is used for the production of 2,2,4- trimethylhexamethylenediamine, which is a precursor for polyamides and polyurethanes. Addition of hydrogen cyanide to the olefinic double bond, followed by amination of the keto group in the presence of hydrogen, gives 3,5,5-trimethyl-3-aminomethylcyclohexylamine [2855-13-2], isophorone diamine. Reaction of the latter with phosgene gives isophorone diisocyanate [4098-71-9]. Both compounds are used in large quantities for the production of polymers, mainly polyurethanes. Worldwide production capacity for isophorone is ca. 50 000 t/a.
