| titleOfInvention | Recovery of pure cyclopentene |
| abstract | IN THE PRODUCTION OF PURE CYCLOPENTENE BY THERMALLY SPLITTING DICYCLOPENTADIENE TO A PRODUCT COMPRISING CYCLOPENTADIENE, HYDROGENATING THE PRODUCT TO CONVERT CYCLOPENTADIENE TO CYCLOPENTENE, AND DISTILLING THE PRODUCT IN A CYCLOPENTENE-DISTILLATE COLUMN TO RECOVER PURE CYCLOPENTENE, THE IMPROVEMENT WHICH COMPRISES DELIVERING THE CYCLOPENTENE-CONTAINING PRODUCT TO BE DISTILLED TO ABOUT THE 60TH TO 90TH TRAY OF A CYCLOPENTADIENE-DISTILLATE COLUMN HAVING ABOUT 100 TO 180 TRAYS, BOILING OFF AT THE HEAD OF SAID COLUMN CYCLOPENTADIENE AND OTHER LOWBOILING COMPONENTS, CONDENSING THE DISTILLATE AND RECYCLING THE MAJOR PORTION THEREOF TO SAID COLUMN TO ESTABLISH A RATIO OF REFLUX TO FEED OF ABOUT 5-15:1, WITHDRAWING AS THE RESIDUE FROM SAID COLUMN A PRODUCT CONTAINING LESS THAN ABOUT 20 P.P.M. OF CYCLOPENTADIENE, AND DELIVERING SAID DISTILLATION RESIDUE TO SAID CYCLOPENTENEDISTILLATE COLUMN, THE RESIDUE IN SAID CYCLOPENTENE-DISTILLATE COLUMN COMPRISING CYCLOPENTANE AND OTHER HIGHBOILING COMPONENTS. |
