Cagliero, Cecilia published the artcileCan the selectivity of phosphonium based ionic liquids be exploited as stationary phase for routine gas chromatography? A case study: The use of trihexyl(tetradecyl) phosphonium chloride in the flavor, fragrance and natural product fields, Category: esters-buliding-blocks, the main research area is phosphonium ionic liquid stationary phase GC; Flavors, fragrances and natural products; Gas chromatography; Ionic liquid stationary phases; Phosphonium based ionic liquids; Selectivity, efficiency and operative temperatures.
Room temperature ionic liquids (ILs) are well established stationary phases (SPs) for gas chromatog. (GC) in several fields of applications because of their unique and tunable selectivity, low vapor pressure and volatility, high thermal stability (over 300 °C), and good chromatog. properties. This study is focused on an IL based on a phosphonium derivative (trihexyl(tetradecyl)phosphonium chloride, [P+66614] [Cl-]), previously shown to be suitable as a gas chromatog. SP because of its unique selectivity. In particular, it aims to establish the operative conditions to apply [P+66614][Cl-] to routine anal. of samples containing medium to high volatility analytes with different polarity, organic functional groups and chem. structure. In the first part, the study critically evaluates long term [P+66614][Cl-] column stability and maximum allowable operating temperatures (MAOT). The relatively low MAOT (210 °C) requires the adoption of a dedicated approach for analytes eluting above this temperature based on a suitable combination of efficiency and selectivity, and column characteristics (length, inner diameter and film thickness) and operative conditions. The performance of [P+66614][Cl-] as a GC SP have been validated through the Grob test, a model mixture of 41 compounds of different polarity, structure, and with different organic functional groups in the flavor and fragrance field, a standard mixture of 37 fatty acid Me esters, some essential oils containing pairs or groups of compounds of different volatility critical to sep. in particular peppermint, thyme, oregano, sandalwood and frankincense. The above approach has produced highly satisfactory separations with all of the samples investigated.
