SummaryThe conditions for reaction of the branched polyfluoroalkylsilane D3CL with silica gel have been examined.From elemental analyses and 29Si NMR spectra it was found that the surface coverage and endcapping of D3CL-coated silica gel (Fluofix | were the same as for ODS packings.The separation behavior of these phases was compared that of a variety of other packings. For polyaromatic compounds and benzene derivatives Fluofix worked in the reversed-phase mode and its retention characteristics were similar to those of C 1 or CN packings. For fluorinated compound the retention characteristics of the phases is similar to those of ODS although with MeOH-water and MeCN-water mobile phases the pressure loss was lower for the fluorinated phases than for ODS.

“…The liquid was purified via vacuum distillation to give a colorless liquid (2.8 g). 1 H NMR measurement indicated that the solution contained 70% (by weight) of the desired product ethynylpentafluorobenzene in pentane. The solution was directly used in the preparation of oligo[1,3-dibutadiynylene-1,3-(tetrafluoro)phenylene].…”

“…This is a direct result of introducing the highly electronegative fluorine heteroatom into the carbon-based stationary phase structure. The strong electron withdrawing power of the fluorine atom produces a very strong bond with carbon that results in stationary phases that are highly hydrophobic and inert [1,2]. In certain cases, these deactivated phases can be utilized in separating reactive chemicals species, such as hydrogen, sulfur and phosphorus as well as metal fluorides [3,4].…”

“…Support coatings with perfluorinated liquid polymers are difficult to prepare due to poor wetting characteristics. Also, these phases show poor thermal stability due to a high temperature coefficient of viscous flow resulting in the disruption of continuous films at high temperatures [1,4]. To ameliorate this effect, support silanization has demonstrated some successes as well as preparing coatings on polytetrafluoroethylene and polychlorotrifluoroethylene supports [1,3].…”

To ameliorate this effect, support silanization has demonstrated some successes as well as preparing coatings on polytetrafluoroethylene and polychlorotrifluoroethylene supports [1,3]. Another approach to improving film stability is the inclusion of polar groups into the fluorocarbon backbone as is the case with poly(perfluoroalkyl) ether Fomblin oils and fluorinated alkyl esters [4].…”
