Isotopic carbon exchange between a simple chloroalkane and dioxins

An isotopic exchange experiment between super(12)C-dibenzo-p-dioxin and super(13)CCl sub(4) at 400 degree C indicates that all the species formed exchange carbon atoms. The reaction produced the components found by investigators of the high temperature equilibria of chloroalkanes. In addition chlorinated phenols, polychlorinated dibenzo-p-dioxins (PCDD's) and polychlorinated dibenzofurans (PCDF's) with super(13)C incorporation in excess of the natural abundancy were detected. Similarly super(12)C-octachlorodibenzo-p-dioxin and super(13)CCl sub(4) exchanged carbon atoms producing pentachlorophenol, octachlorodibenzo-p-dioxin and octachlorodibenzofuran with super(13)C in excess of the natural abundancy.
