ABSTRACT:
3-Hydroxy-3-methylglutaric acid is prepared by electrolysis of an aqueous alkaline solution of 3-methyl-1,3,5-pentanetriol using anodes coated with nickel oxide/hydroxide NiO(OH) and conventional cathodes, followed by acidification of the alkaline solution and conventional working up. The yields achieved by this are always between about 70 and 85% of theory.
