Abstract
The dependence of the variations in the differential molar free energy of sorption of polyfluorocarboxamides R(F)C(O)NR(2) (R(F) = CF3(CF2)( i), i = 0 to 5, R = H or Me) on capillary columns on the molecular str ucture of the amides, the temperature of analysis, and the nature of t he stationary phases (OV-101, XE-60, and PEG-40M) were investigated by GLC. The peculiarities of the variation of the sorption characteristi cs of amides in XE-60 and PEG-40M polar phases, which cause the invers ion of the order of retention of the members of pseudohomologous serie s, were found.
