Phase equilibria in the decane–urea–ethanol system were investigated between 15° and 40°C. Solubility limits for urea–decane adduct in ternary liquid solutions and for urea in ethanol were measured over the entire feasible range of compositions, thus defining the phase diagrams. Activity coefficients estimated for the saturated liquid solutions reflected strong positive deviations from ideality. The magnitudes were consistent with the results of independent vaporliquid equilibrium studies.
