PROCESS FOR THE PREPARATION OF PINACOLONE

摘要

Pinacolone is prepared by adding 2,3-dimethyl-2-butene and an aqueous solution of hydrogen peroxide at a temperature of 20 DEG to 90 DEG C. to a solution which contains water and one or more carboxylic acids having 1 to 8 C atoms and which can, if desired, also contain small amounts of a strong acid, increasing the temperature after substantial or complete reaction of the hydrogen peroxide, and distilling off as an azeotropic mixture with water the pinacolone formed.
