Formation of Polychlorinated Dibenzo-p-Dioxins and Their Thermal Decomposition Products from Pyrolysis Reactions of Chlorophenates

  • Published : 1995.12.25


Polychlorodibenzo-p-dioxins(PCDDs) have been prepared by microsacale pyrolysis of trichlorophenates. During the pyrolysis reaction, dechlorinated dibenzo-p-dioxins were also formed by the thermolysis of PCDDs. The dechlorination pathways of PCDDs were suggested in this reaction. The identification of these products was performed using capillary column gas chromatography-mass spectrometry.
