Extraction of polyaromatic hydrocarbons by methanol solutions of organic salts
Abstract
Novel extraction systems consisting of an aliphatic hydrocarbon and an organic salt methanol solution have been investigated. UV-spectrophotometry and HPLC have been used to determine the concentration of aromatic hydrocarbons in phases of system. 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-butyl-3-methylimidazolium chloride and 1-methylquinolinium benzenesulfonate in methanol possess high affinity for aromatic hydrocarbons, while solutions of salts containing aliphatic cation or aromatic anion do not show such affinity. Explanation of these phenomena has been given.
