| titleOfInvention | Preparation method of ion exchange resin for sulfolane purification |
| abstract | The invention discloses a preparation method of ion exchange resin for purifying sulfolane, which adopts macroporous chloromethylated polystyrene resin as a raw material to react with pyridine functional groups and substituted derivatives thereof to obtain chlorine type anion exchange resin, and then uses hydroxyl to replace chloride ions in the resin to obtain the anion exchange resin for purifying sulfolane. Compared with the conventional anion exchange resin, the ion exchange resin prepared by the method has excellent heat-resistant stability, is more effective in deionization when being used for sulfolane purification equipment, and has longer service life. |
