Thin-layer and gas chromatography of some fluorobiphenyls and fluoronaphthalenes

Relative retention data are reported for biphenyl, naphthalene, seven fluorine substituted biphenyls (bearing 1, 2, 8, and 10 fluorine atoms per molecule), and mono- and octafluoronaphthalenes in gas chromatography with (a) silicone fluid DC 710, (b) Carbowax 20M, and (c) Bentone 34-silicone fluid D...

Description
Summary:Relative retention data are reported for biphenyl, naphthalene, seven fluorine substituted biphenyls (bearing 1, 2, 8, and 10 fluorine atoms per molecule), and mono- and octafluoronaphthalenes in gas chromatography with (a) silicone fluid DC 710, (b) Carbowax 20M, and (c) Bentone 34-silicone fluid DC 710 and in thin-layer chromatography on (d) silica gel and (e) alumina. With a and d retention generally decreases with increasing number of fluoro substituents, n, and, for a given n, is higher for a biphenyl compound than for a naphthalene one. 2,2′-Difluorobiphenyl is an exception in d, since it has the smallest R F of the various solutes. Some irregularities in these trends are found in cases b, c and e.
