  Zol-gel process was used to synthesize equilibrium mixtures of mono-, di-, and trimester derived from trimethylolpropane and perfluorocarboxylic acids. The elution order of the components of the mixtures from a weakly polar HP-5 column was established. The mass spectra of the synthesized compounds were studied. The GC-MS parameters of the products were compared with the respective parameters of their nonfluorinated analogs. The characteristics of the fluorinated esters have features determined by the esterification degree and the nature of the perfluoroalkyl groups, due to which these compounds can be identified in mixtures.
