ORDER OF THE REPLACEMENT OF HYDROGEN BY HALOGEN IN THE HALOGENATION OF DIBENZO-p-DIOXIN AND ITS NITRO AND AMINO DERIVATIVES

The order of the replacement of hydrogen by halogen in the bromination and chlorination of dibenzo-p-dioxin and its nitro and amino derivatives was examined with the purpose of determining the possibilities of the formation of highly toxic isomers of halogenated dibenzo-p-dioxins from precursors with a tricyclic structure of dibenzo-p-dioxin.A number of halogenated dibenzo-p-dioxins were synthesized, which illustrates the order of the replacement, and their physicochemical and spectral characteristics are given.

FORMATION OF HETEROCYCLIC HAZARDOUS COMPOUNDS BY THERMAL DEGRADATION OF ORGANIC COMPOUNDS

2,3,7,8-Tetrabromodibenzofuran in ppm concentrations can be generated via reductive debromination and subsequent intramolecular cyclization during thermolysis of polybrominated aromatic compounds such as decabromodiphenyl ethers which are used as flame retardants in plastics.The respective tetrabromobenzodioxin isomer is produced in moderate amounts.In analogy to the chlorinated isomers the formation of toxic substances from incineration or fire accident constitutes a potential hazard.
