| titleOfInvention | A kind of preparation method of aromatic amine antioxidant 5057 |
| abstract | The invention discloses a kind of preparation method of aromatic amine antioxidant 5057.Diphenylamines and SO 4 2‑ /SiO 2 ‑TiO 2 Type solid super-strong acid is added in reactor, 140~170 DEG C are heated under stirring, then start to be added dropwise diisobutylene after 140~170 DEG C of stirring reactions, solid super-strong acid is recovered by filtration, filtrate is removed by vacuum distillation after unreacted diphenylamines, is handled by activated carbon decolorizing and is just obtained aromatic amine antioxidant 5057.Catalyst of the present invention is recyclable by simple filtration, it is to avoid use AlCl 3 Etc. the catalyst of larger pollution can be produced；And catalyst activity is high, consumption is few, with good catalytic effect, and recycling can be achieved, the discharge of solid waste is reduced. |
