use	organic synthesis intermediate.
production method	under rapid stirring, dry isobutylene is introduced into the mixture of benzene and sulfuric acid, the reaction is exothermic, the reaction temperature is about 15 ℃, the reaction is ventilated for 1-1.5h, the reaction is stirred for 1h, the sulfuric acid layer is separated, and a small amount of water is added to the oil layer to precipitate 1,4-di-tert-butylbenzene crystals. The oil layer is fractionated to obtain benzene, tert-butylbenzene and p-di-tert-butylbenzene.
