Formation of PCDDs and PCDFs from anthracene and chloroanthracene in a model fly ash system.
Anthracene and 2-chloroanthracene have been investigated as model compounds for carbon in the formation of PCDDs and PCDFs. The formation of PCDDs and PCDFs from anthracene reaches a maximum around 300 °C. Many chlorinated products beside PCDDs and PCDFs are identified after formation from 2-chloroanthracene, including chlorinated anthracenes, naphthalenes, and benzylnaphthalenes. This suggests that part of the PCDDs and PCDFs formed from anthracene probably comes from recombination of its degradation products.
