The solubility of oxyethylated nonylphenols (neonol AF 9-12 and neonol AF 9-25) in aqueous solutions of inorganic salts is studied at 25°С. Cation and anion abilities to salt out neonols from aqueous solutions are examined. It is found that anions are able to salt out neonols while cations are able to salt in neonols. The concentration parameters of extraction in water–neonol AF 9-12 (neonol AF 9-25)–(NH4)2SO4 systems are optimized.
