Abstract
Hexachlorocyclopentadiene is produced by contacting pentane, pentene, cyclopentane or cyclopentene or chlorinated derivatives thereof with a molten salt mixture of cuprous and cupric chloride. Cyclopentadiene can also be employed as an initial feed, in which case the cyclopentadiene is initially chlorinated to effect saturation thereof, followed by contacting of the chloro substituted cyclopentane with a molten salt mixture of cuprous and cupric chloride to produce hexachlorocyclopentadiene.
