SPECTROSCOPIC CHARACTERIZATION OF ENVIRONMENTALLY RELEVANT C-10-CHLOROTERPENES FROM A PHOTOCHEMICALLY MODIFIED TOXAPHENE STANDARD

Twenty-five pure environmentally relevant toxaphene components have be en isolated from photochemically modified technical toxaphene by means of a combination of column chromatography on silica gel and preparati ve high resolution liquid chromatography. These compounds are 6 chlori nated camphenes (1-3, 5, 7, and 11) and 19 chlorinated bornanes (4, 6, 8-10, 12-16, 18-24, 26, and 27 according to Table 1). Two further chl orobornanes (17 and 25) have been isolated from a highly chlorinated m ixture obtained by the excess chlorination of 2-exo,10-dichlorobornane . The structural elucidation of the isolated compounds has been carrie d out with spectroscopical methods.
