The sulfonation of 2-tert-butylphenol with chlorosulfonic acid in dichloromethane at -30 deg C has been studied.A total of 13 acids have been identified in the reaction mixture.They are derivatives of phenol, 2-tert-butylphenol, 4-tert-butylphenol and 2,4-di-tert-butylphenol.First-order rate constants have been obtained for most of the reactions and a two-phase reaction mechanism is discussed with respect to direct sulfonation, sulfate ester rearrangement and ipso sulfonation.
