Heat of mixing data for 12 binary systems are obtained using a calorimeter designed previously by Nagata, et al. (1972). Experimental data are well correlated by a modification of Guggenheim''s equation derived for a system of triplets. The proposed equation is applied for a simultaneous fit of the excess Gibbs free energy and heat of mixing data for three binary systems.
