Interfacial tension in cooled heterogeneous liquid acetonitrile–ethyl acetate–isopropanol–water–phenol systems

详细

It is found that the tension at the interfacial boundary of liquid phases formed by mixtures of acetonitrile–ethyl acetate–isopropanol (85 : 15 : 0 and 80 : 15 : 5 vol/vol/vol %) and water at 263 K falls exponentially as the concentration of phenols grows within 0–1 mg/mL. It is shown that the relatively low values of interfacial tension (11–32 mN/m) observed in cooled heterogeneous systems promote the redistribution of phenols between two liquid phases.
