Chlorostyrenes in fish and sediment samples from the river Elbe

Chlorinated styrenes were identified in fish (bream) and sediment samples from the river Elbe. Four hexachlorostyrenes, four heptachlorostyrenes (concentrations in fish 1-10 ng/g wet weight) and octachlorostyrene (10-45 ng/g wet weight) were analysed. The gas chromatographic retention times and the electron impact (EI) mass spectra of the respective hepta- and hexachloro congeners found in the environment as well as those of some synthesised compounds are presented and discussed. The comparison of the chromatograms from the samples in the upper part of the river with those from the estuary revealed a possible difference in the pattern of chlorostyrenes.

NOVEL PRODUCTS IN THE CO2-LASER INDUCED REACTION OF TRICHLOROETHYLENE

Previous report on the thermal or CO2-laser induced decomposition of trichloroethylene have identified only one condensable product, hexachlorobenzene (in addition to HCl and mono- and dichloroacetylene).We have found that trichloroethylene vapor exposed to cw irradiation on the P(24) line of the (001-100) band of the CO2 laser at incident power levels from 8-17 W procedures numerous products, of which the 13 major ones have been identified using IR, GC/MS, GC/FTIR, and NMR methods.All of these products have 4, 6, or 8 carbons, are highly unsaturated, and are completely chlorinated or contain a single hydrogen.C4HCl5 and C6Cl6 isomers (three of each) account for ca. 55percent to 85percent of total products (based on peak area in the total ion chromatograms in GC/MS runs), depending on reaction conditions.In addition to characterizing the products, we discuss the dependence of the product distribution on laser power, irradiation time, and cell geometry, and we outline a possible mechanism.

Syntheses and Properties of Hexa- and Heptachlorostyrenes with Fully Chlorinated Aromatic Nuclei

All six possible hexa- and heptachlorostyrenes with fully chlorinated aromatic nuclei have been synthesized.Their ultraviolet and infrared spectra are discussed, fragmentation in the mass spectrometer described and from the 1H and 13C NMR spectra all para
