ABSTRACT:

Surface tension of three ternary mixtures of n-hexane-cyctohexane, benzene, cyclohexane-n-heptane-toluene and n-pentane-n-hexane-benzene has been evaluated at 298.15 K by extending Brock and Bird relation. Results obtained have been compared with experimental values to test validity of the relation. Interaction has been studied in terms of excess surface tension.
