  A process for the production of a disubstituted hydroquinone which comprises alkylating hydroquinone in the presence of a sulphonic acid condensation catalyst with an olefin or a substance which under the reaction conditions acts as a source thereof. The preferred olefin is 2-methyl-2-butene either alone or in admixture- with isomers thereof, and the preferred catalyst is methane sulphonic acid and the reaction product is 2,5-di-tert-amylhydroquinone. Only catalytic amounts of catalyst are required. The reaction product is worked-up by complete dissolution of the desired product and washing with an aqueous medium containing a pH buffering agent and a reducing agent.
