Octachloronaphthalene is a chemical compound from the group of organic aromatic halogenated hydrocarbons . It is one of the polychlorinated naphthalenes that were added to Appendices A and C of the Stockholm Convention in 2015 .

Extraction and presentation

Octachloronaphthalene can be obtained by reacting naphthalene in sulfuryl chloride with chlorine and iron (III) chloride or iron .

It is also possible to produce it by reacting naphthalene with chlorine in the presence of antimony (V) chloride at 150 to 210 ° C.

properties

Octachloronaphthalene is a yellowish solid that is practically insoluble in water.
