SYNTHESIS AND PROPERTIES OF HALOGENATED DERIVATIVES OF DIBENZO-p-DIOXINE CONTAINING A TRIFLUOROMETHYL GROUP

Article abstract of DOI:10.1007/BF01169633

Methods of preparation of a series of polyhalogenated dibenzo-p-dioxines containing the trifuoromethyl group in the 2 position are described.The physicochemical properties of these compounds are studied, electron impact mass spectra are discussed, and relative retention times are measured.In their gas-chromatographic and mass-spectral characteristics, some of the synthesized compounds are suited for use as internal standards in the quantitative determination of polychlorinated dibenzo-p-dioxines and dibenzofurans in the environment by means of the chromato-mass-spectrometric method.
