Abstract
A process for producing cyclopentane from by-product streams containing cyclopentene consists of distilling the cyclopentene from the feedstream and then hydrotreating the cyclopentene-containing fraction to cyclopentane. A second distillation step may then be employed to remove the hydrocarbons which are lighter than cyclopentane. The process has particular applicability in the treatment of feedstreams containing neo-hexane. The cyclopentene is easily separated from the neo-hexane in a conventional fractionator.
