INVERSE GAS-CHROMATOGRAPHY IN CHARACTERIZATION OF SURFACTANTS - DETERMINATION OF BINARY PARAMETER

Binary parameters corresponding to hydrogen bonding (I-12b) and polar (I-12p) interactions were determined by inverse gas chromatography. Th e influence of the structures of broad-range and narrow-range distribu ted oxyethylene derivatives of 1-hexadecanol on the binary parameters was studied. The relationship between the binary parameters (I-12h and I-12p) and the polarity of the compounds used as stationary phases is presented and discussed, in addition to the effect of the solubility parameter and its increments on the values of the two binary parameter s.
