PRODUCTION OF POLYMERIZATION GRADE DICYCLOPENTADIENE |
摘要 |
A process for purifying crude dicyclopentadiene which comprises the steps of : cracking the crude dicyclopentadiene to form a monomeric-containing effluent which comprises at least one monomer selected from the group consisting of: C4 acyclic dienes, C5 acyclic dienes, cyclopentadiene and methylcyclopentadiene ; separating the monomeric-containing effluent into a cyclopentadiene-enriched stream and a cyclopentadiene-poor stream; dimerizing the cyclopentadiene- enriched stream to form a dimerizer effluent; contacting a membrane separato r under pervaporation conditions with the dimerizer effluent wherein the C4 acyclic dienes, C5 acyclic dienes and cyclopentadiene permeate through the membrane separator and wherein a dicyclopentadiene product having a purity o f at least about 98 % is retained as retentate, is disclosed. Also disclosed i s an apparatus for carrying out said process.
