The (solid?liquid) phase equilibria (SLE) of binary mixtures containing fragrance raw materials \heptan-2-one, or nonan-2-one, or undecan-2-one, or dodecan-2-one, or tridecan-2-one + octan-1-ol, or decan-1-ol, or dodecan-1-ol\ were investigated. These systems have been measured by a dynamic method over a wide temperature range from (230 to 300) K and ambient pressure. All binary systems revealed simple eutectic mixtures with complete miscibility in the liquid phase. The experimental data were correlated by the UNIQUAC, NRTL, and Wilson equations, utilizing parameters derived from the SLE. The standard deviations of the solubility temperatures were (0.52, 0.52, and 0.46) K for the UNIQUAC, NRTL, and Wilson equations, respectively. The Mod. UNIFAC (Do) representation of the SLE with known, literature parameters has given very good results.
