Abstract

A process for preparing trimethylhydroquinone diacetate, with subsequent hydrolysis to give trimethylhydroquinone, the process including reacting 2,2,6-trimethylcyclohexane-1,4-dione under oxidative conditions, in the presence of a sulfonating agent and a strong acid, and in the presence of an acylating agent.
