Summary:An aqueous two-phase system based on polyethylene glycol-1500 and sodium sulfate for the extraction of a number of monocarboxylic acids from aqueous solutions has been studied. The influence of the phase contact time, system composition, the molecular weight of the polymer, and temperature on the quantitative characteristics of the interphase distribution of a number of aliphatic monocarboxylic acids has been investigated. Based on the results, it is concluded that these systems are effective for solving problems of the extraction, separation, and purification of carboxylic acids and they are promising as extraction systems for the extraction of metal salts in the presence of carboxylic acids.
