ABSTRACT:
Process for the production of 3,3-dimethylglutaric acid from isophorone. In a first step the isophorone is converted with ozone into an ozone-addition product. The ozone-addition product is converted by hydrolysis into 3,3-dimethyl-5-oxohexanoic acid. The latter is converted into 3,3-dimethylglutaric acid by treatment with hydrogen peroxide.
