Correlations between physical properties of halogenated alkanes and their gas chromatographic behaviour on polar and non-polar stationary phases : Linear chloro-, bromo- and iodoalkanes

Abstract

Normal alkanes and linear chloro-, bromo- and iodoalkanes with the halogen atom in the 1-, 2- and 3-positions have been analyzed on Apiezon L, tricresyl phosphate and Carbowax 20M columns at 75°, 100° and 125°C, using a flame ionization detector. The retention times and retention indices relative to normal iodoalkanes were determined for every compound, and their relationships with the stationary phase and the analysis temperature were investigated. The relationships between the retention data and the following physical properties were also studied: molecular weight, boiling point and molecular volume.
