Abstract
Abstract The reversed-phase liquid chromatography of structural isomers of alkylphenols has been studied. Octyl-bonded silica gel was useful as stationary phase and addition of a trace of triethylamine to the eluent was effective for this purpose. The separation of nine structural isomers of alkylphenols, ethylphenols and xylenols, was accomplished by such liquid chromatographic system. Thus the good reproducibility of the capacity ratios was obtained. The increase of retention of the solute was not observed by addition of the ion-pair reagent to the eluent.
