Gas chromatographic properties of tetrafluoroethylene telomers

Abstract

The paper describes an investigation of the gas chromatographic properties of tetrafluoroethylene telomers of general formula F(CF2)nI, Br(CF2)nBr, Br(CF2)nI, I(CF2)nI and (CF3)2CF(CF2)nI. The telomers are well resolved on columns with squalene, silicone oil or tritolyl phosphate stationary phases, and relative retention volumes are given for these three columns. The temperature dependence of the relative retention volumes of F(CF2)nI and Br(CF2)nBr telomers has been investigated. The relative retention volumes are correlated with the telomer boiling points, and with structural features of the telomers. © 1974.
