EXTRACTION OF VARIOUS AROMATIC HYDROCARBONS BY METHANOL SOLUTIONS OF 1-METHYLPHENANTHROLINIUM BENZENESULFONATE

Extraction systems consisting of n-heptane and 1-methylphenanthrolinium benzenesulfonate methanol solution have been investigated. Distribution constants in systems n-heptane – polar phase for aromatic hydrocarbons and the increments of methylene group have been calculated. It has been found that the polar phase is highly structured and has a large increment of the methylene group. It has been also found that solutions of 1-methylphenanthrolinium benzenesulfonate
in methanol possess high affinity for condensed aromatic hydrocarbons, which value exceeds all the previously studied extraction systems. Extraction of hydrocarbons with isolated aromatic systems by 1-methylphenanthrolinium benzenesulfonate methanol solution is negligible. The systems studied can separate condenced polyaromatic hydrocarbons from hydrocarbons with isolated aromatic systems. The effect found may be used for preparing modified state phases in liquid chromatography.
