| titleOfInvention | The preparation method of aromatic liquid amine antioxidants 5057 |
| abstract | The present invention discloses a kind of preparation method of aromatic liquid amine antioxidants 5057; Utilize perfluorinated sulfonic resin as solid acid catalyst, be that 1:0.2 ~ 0.5 joins in reactor pentanoic and perfluorinated sulfonic resin with mass ratio, then 150 ~ 180 DEG C are heated under stirring, then diisobutylene was added drop-wise in reactor within 60 ~ 120 minutes, the mol ratio of diisobutylene and pentanoic is 1.2 ~ 1.4:1; At 150 ~ 180 DEG C of stirring reactions after 6 ~ 10 hours, filtered and recycled perfluorinated sulfonic resin, filtrate, after underpressure distillation removes unreacted pentanoic, just obtains aromatic liquid amine antioxidants through activated carbon decolorizing process.The present invention, compared with existing synthetic method, has simple to operate, product and is easy to separating-purifying, and catalyzer one way long catalytic life also can repeatedly use and the advantage such as regeneration, is suitable for industrialization cleaner production. |
