Thermolysis of phenoxyaluminum compounds and formation of PCDD/F and their precursors

Article abstract of DOI:10.1016/0045-6535(94)90370-0

Within the study of the formation of chlorinated dioxins and dibenzofurans and their precursors the thermolysis of hexachloroethane over the aluminum melt was investigated. "De novo" synthesis of precursors of PCDD/F was studied in the model system AlCl₃/elemental carbon. Totally chlorinated heterocyclic compounds have been detected parallel with the formation of organochlorine compounds. The possibility of inserting oxygen to aluminum organyls was presented. In order to gain more detailed knowledge of the catalytic behaviour of fly ash the chemistry of thermolysis of phenoxy- and chlorophenoxy aluminum compounds at 300°C with the presence and absence of Al₂O₃ was investigated. Reagent compounds and products of thermolysis were followed by mass spectrometry.
