Synthesis of the 38 Tetrachlorodibenzofuran Isomers and Identification by Capillary Column Gas Chromatography/Mass Spectrometry

Article abstract of DOI:10.1021/ac00252a028

The 38 positional isomers of tetrachlorodibenzofuran have been synthesized by pyrolysis of specific polychlorinated biphenyl congeners, ultraviolet photolysis of pentachlorodibenzofurans, and chlorination of trichlorodibenzofurans by aromatic substitution.The specificity of these reactions in combinatiuon with capillary column gas chromatography with mass spectrometric detection has allowed each of these isomers to be identified based on their relative elution order.
