Abstract

Abstract Measurements of liquid—liquid equilibria in the system n-butyl alcohol—saline water have been carried out at 20, 30 and 40 °C.A theoretical treatment is given to calculate the salting coefficient k s by a perturbation method in the case of liquid—liquid equilibrium. An intermolecular potential is assumed to describe the polar interactions of the non-electrolytes.Calculated values of k s are compared with experimental values.
