The chromatographic characteristics were investigated for eight aromatic derivatives of 3-chloro-1,4-naphthoquinone under conditions of normal-phase thin-layer chromatography for benzene-based binary mobile phase and such polar solvents as chloroform, acetone, acetonitrile, methanol and propan-2-ol. The slope of linear retention dependencies for the investigated compounds on the concentration of the polar component in the mobile phase satisfactorily correlates with the area occupied by the adsorbed analyte molecule in the stationary phase. The intercept in the Soczewinski equation depends on the polar component of the mobile phase.
The chromatographic characteristics are investigated for six derivatives of 1,4naphthoquinone under conditions of normal-phase thin-layer chromatography for benzene-based binary eluent and such enhancing polar solvents as chloroform , acetoneand propan-2-ol. The slope in the Soczewinski equation for the investigated compounds satisfactorily correlates with the area occupied by the adsorbed solute molecule in the stationary phase.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
