Abstract
The retention behavior of 57 mono- or polyhalogenated biphenyls was characterized by gas chromatography on a DB-210-CB capillary column and by high-pressure liquid chromatography on ODS phases. A possible relationship between the recorded retention data (Kovats index) and molecular surface area was explored. Generally, the addition of halogen atoms (Cl, Br, I) to biphenyl increased both the retention index and the calculated molecular surface area for the series of polyhalogenated biphenyls investigated. The addition of fluorine however resulted in a decreased retention index although the molecular surface area was slightly increased. The addition of halogen substituents resulted in more dramatic changes in retention as demonstrated by the Kovats index (IK) for gas chromatography than for liquid chromatography. The homologues with chloro or bromo substituents in ortho positions displayed lower IK values than those with halogens in meta and para positions. Generally, good correlation was observed between IK and the calculated molecular surface area values. © 1988, American Chemical Society. All rights reserved.
