Abstract

Described below is a process to prepare commercial 3-hydroxy-3-methylglutaric acid through oxidisation of 3-methyl-1,3,5-pentanetriol using nickel salt as a catalyst. Oxidisation can be done using hypochlorite from an alkaline or earth alkaline metal, or sodium sulphate. In this way prepare 3-hydroxy-3-methylglutaric acid is obtained that has a high purity and a higher yield.
