Abstract:The use of the hexane-2,2,2-trifluoroethanol heterophase system of solvents in partition chromatography is characterized. Gas-chromatographic retention indices and partition coefficients are used for the identification of organic compounds in this technique. The partition coefficients of compounds from 12 homologous series were measured in this heterophase system, and parameters for their group identification were calculated. The examples of the use of this system for solving different analytical problems are considered.
