| titleOfInvention | A kind of extract the method for dicyclopentadiene in cracking of ethylene C9 |
| abstract | The invention discloses and a kind of utilize reversible Diels-Alder reaction to extract the new method of dicyclopentadiene in cracking of ethylene C9, belong to field of chemical separation and purification.The method includes the preparation of extractant, C9 extracts, dicyclopentadiene reclaims and extractant regeneration.Extractant is made up of water solublity benzoquinone sulfonate, Lewis acid catalyst, phase transfer catalyst and water；C9 is carried out single-stage by extractant or Multi-stage heating extracts, until the clearance of the dicyclopentadiene in C9 reaches requirement；Regenerate after the heated decylization pentadiene of loaded extractant, can be recycled.Present invention process is simple, and easy to operate, processing cost is low, has broad application prospects. |
