Cyclopentadiene → Dicyclopentadiene

Participants

Reaction Steps

In a process for the production of cyclopentene from dicyclopentadiene which comprises splitting dicyclopentadiene under heat to form cyclopentadiene; partially hydrogenating the cyclopentadiene to form a crude cyclopentene containing an impurities fraction boiling at a higher boiling point than cyclopentene and containing cyclopentane; purifying the crude cyclopentene by distillation in which said impurities fraction is separated from the crude cyclopentene; the improvement which comprises recycling at least part of the separated impurities fraction as the impurities fraction is produced in said distillation to the dicyclopentadiene splitting stage, said separated impurities fraction comprising predominantly cyclopentane.
