Isolation and gas chromatographic characterization of some toxaphene components.
Column chromatography of technical toxaphene on activated alumina reproducibly yields eight major fractions from which 2,2,5-endo,6-exo,8,9,10-heptachlorobornane and 2,5,6-exo,8,8,9,10-heptachlorodihydrocamphene may be readily isolated by preparative gas--liquid chromatogrpahy. These and some other reported toxaphene components were characterized by gas--liquid chromatographic retentions relative to aldrin on packed columns of OV-101, OV-17, and QF-1, and on a capillary open-tubular column of OV-101. Structural assignments were revised for some components on the basis of retentions. The fractionation and isolation procedure may have general utility for separating toxaphene components, and the retention data form a convenient basis for component comparison.
