Abstract: The relationship between activity coefficient and molecule-exchanging energy of surfactants in the surface monolayer of binary surfactant aqueous solutions has been deduced with the help of two-dimensional crystal model. The results show the relationship between the synergism of surfactants and the molecule-exchanging energy. Through the parameter of molecule interaction( βs), the value of the molecule-exchanging energy can be obtained by equation ε =2.3×10-24 βs T that has been examined with six typical surfactant systems.

Key words: Surfactant, Molecule exchanging energy, Parameter of molecule interaction( βs)
