| 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. |
