The reaction converts the alpha-isophorone directly to ketoisophorone without the intermediate isomerization of alpha-isophorone to beta-isophorone (3,5,5-trimethyl-3-cyclohexenone).

A method of manufaturing 2,6,6-trimethyl-2-cyclohexen-1,4-dione (ketoisophorone) from 3,5,5-trimethyl-2-cyclohexenone (alpha-isophorone).

The invention relates to the use of β-isophorone as solvent.

Preferred organic substituents are alkyl, aryl, and isophorone groups.

Process for the selective preparation of β-isophorone epoxide by epoxidation of β-isophorone with organic percarboxylic acids at a water content of less than 5 wt.%.

3,5,5-trimethyl-2-cyclohexen-1-one, also known as isophorone, is an industrial chemical.

Coal-tar creosote, Dimethyl formamide, Dioctyl phthalate, Isophorone, and Rhodamine B are no longer found in registered pest control products in Canada.

The main products concerned are Diacetone Alcohol (DAA), MethylIsoButylKetone (MIBK), MethyIsoButylCarbinol (MIBC), Hexylene Glycol (HG), and Isophorone (IPHO).
