The solubility of 1,4-dioxan-2-one (1) in ethyl acetate (2) was measured over the temperature range from 263.55 K to 295.95 K. The results were correlated by an exponential equation. Densities of their binary mixtures have been measured at temperatures from 263.05 K to 298.55 K and at mole fraction x, of 0.2010 to 0.7099. The metastable zone width was measured for the evaluation of the nucleation rate and nucleation temperature. Results for the density and the metastable zone width were correlated by empirical equations.
