Abstract: Based on Butler's equation and the relationship of phase equilibrium, this article suggests a scries of generalized equations for calculating phase equilibrium among the bulk phases and the interface phase. By using the equations proposed in this paper, the interfacfal mole fractions and the inter-facial adsorption amounts of the surfactant solutions can be calculated, and the calculation for several practical systems was carried out and the results obtained are satisfactory.Based on the experimental phenomena and calculated results, a physical model for the interface phase is suggested, the interaction among the surface active substances in the interface phase is also discussed and a lot of useful information are applied to the researches of emulsion, microemulsion etc.
