Abstract
Provided is an improved process for preparing 2-(1-phenylethyl)hydroquinone and its diacetate salt. In this process, the differential solubility of product and starting materials hydroquinone and styrene in non-polar organic solvents is utilized to provide mono-alkylated materials which can be easily removed from the reaction mixture. A solid acid catalyst is also used which allows the isolation of product and recycle of unreacted starting materials to be accomplished on an industrial-scale continuous process.
