PROBLEM TO BE SOLVED: To provide a method for producing a tertiary butoxybenzene derivative by reacting a phenol compound with isobutylene in the presence of an acid catalyst, by which the unreacted isobutylene can quantitatively and efficiently be removed, recovered from the reaction solution and recycled. SOLUTION: This method for producing the tertiary butoxybenzene derivative by reacting a phenol compound with isobutylene in the presence of an acid catalyst, comprises (1) quantitatively dropping the reaction solution on a hot alkali aqueous solution to remove the unreacted raw materials and then distilling the residue to obtain the tertiary butoxybenzene derivative, or (2) quantitatively dropping the alkali-treated reaction solution on a heating medium to remove the unreacted raw materials and then distillingthe residue to obtain the tertiary butoxybenzene derivative.
