Polychlorinated thianthrenes

Polychlorinated Dibenzothiophenes (PCDTs), Thianthrenes (PCTAs) and Their Alkylated Derivatives... [Pg.289]

OCTA and HeptaCTAs are formed, along with other polychlorinated aromatic sulfur compounds, as by products in the synthesis of pentachlorothiophenol from hexachlorobenzene. Pentachlorothiophenol is used as an additive for the improvement of the vulcanization process of rubber in the tire industry. The formation of OCTA is believed to occur by dimerization of pentachlorothio-phenate and by intramolecular cyclization and the formation of HeptaCTAs by dechlorination of higher chlorinated thianthrenes [27]. [Pg.292]
