Abstract
A process for producing 3,5-di-tert-butylbenzenesulfonic acid includes forming a solution of 1,3,5-tri-tert-butyl benzene in a solvent, exposing said solution to anhydrous hydrogen chloride gas, and reacting 1,3,5-tri-tert-butylbenzene with a sulfonating agent to form 3,5-di-tert-butylbenzenesulfonic acid. Said exposing of said solution to anhydrous hydrogen chloride gas is carried out before reacting said 1,3,5-tri-tert-butylbenzene with said sulfonating agent. The process also includes recovering said 3,5-di-tert-butylbenzenesulfonic acid.
