Abstract

The retention of 29 aniline derivatives was determined by high performance liquid adsorption chromatography using an alumina column and dichloromethane-n-hexane mobile phases in various vol. ratios. The retention parameters of anilines (log k′ and the slope and intercept value of the correlation between log k′ and the dichloromethane concentration in the eluent) were correlated with the physicochemical parameters (lipophilicity and adsorption capacity of silica) of aniline derivatives. The retention of anilines decreased with their increasing lipophilicity and increased with their increasing silica adsorption capacity. The alumina columns was found to be an appropriate support for the adsorptive phase separation of polar compounds as aniline derivatives.
