Abstract

The separations of various nonionic tensides consisting of ethyleneoxide oligomer mixtures were carried out in 55 different thin-layer chromatographic systems. The solvent strength and selectivity are calculated for each chromatographic system and correlated with the physicochemical parameters of solvent using stepwise regression analysis. Selectivity was higher on alumina than on silica layer. Both strength and selectivity depended significantly on the dielectric constant and refractive index of the solvents; however, correlation differed considerably and was nonlinear. Both solvent strength and selectivity were influenced chiefly by dielectric constant (70-73%), whereas the effect of refractive index was lower (27-30%).
