More Information
Summary:The present invention discloses a negative ion polymerization solvent refining process, wherein a dimer produced through self-polymerization of cyclopentadiene can be adopted as a heavy component and is removed through heavy component removing, and the negative ion polymerization solvent refining process is designed into a dewatering, heavy component removing and light component removing process. With the process of the present invention, the residual cyclopentadiene in the refined solvent obtained through the process is extremely less, the influence of the cyclopentadiene on the polymerization job during the use of the refined solvent is effectively avoided, and the production stability and the product quality are improved.
