PAHReactions in thePresence of
Hexachlorocycopentadiene and
Hexachlorobutadiene
•
PAHs have been known to spontaneouslychlorinate in the presence
hexachorocyclopentadiene andhexachlorobutadiene.
The reaction is a
substitution reactionwith chlorine for hydrogen on thePAH.
The exact
mechanismhas not been determined at this time.
No loss of
hexachlorocyclopentadiene nor hexachlorobutadiene is seen in this reaction.
•
The reaction is believed tobe caused by free chlorine or chlorine radicals in
certain lots of hexachlorocyclopentadiene and hexachlorobutadiene.
•
Purificationof hexachlorocyclopentadiene and hexachlorobutadiene by
distillationprevents this reaction.
