 Critical Evaluation:
        A survey of reported compositions along the solubility curve (soly) and compositions of coexisting liquid phases in equilibrium (equil.) for the system nitromethane + 1-nonanol + naphthalene is given in Table 1.

Solubility data

         The system nitromethane + 1-nonanol + naphthalene includes a three-phase region, although only one binary pair of components, nitromethane + 1-nonanol, are partially miscible. The data for this system were compiled and critically evaluated.3 The UCST (upper critical solution temperature) of the binary system nitromethane + 1-nonanol has been reported in Sazonov and Chernysheva1 as 327.96 K and to agrees with the recommended value in Sazonov et al.3
         The solubility temperatures of the liquid and solid phases were determined1 by the synthetic method in ternary mixtures with constant mass content of naphthalene, and also in ternary mixtures with a constant relationship of (1) and (2). Experimental errors were reported in Sazonov and Chernysheva1 as ± 0.02 K (for liquid phases) and ± 0.03 K (for solid phase). Maximal temperature of the three-phase equilibrium was reported to be as 298.1 K (Ref. 1). Between 298.1 K and 327.96 K exist two separate regions of two-phase state, one of them can be described by a band type curve.

Liquid-liquid equilibrium data
         Compositions of two and three coexisting phases for the ternary system nitromethane + 1-nonanol + naphthalene were determined in Sazonov and Chernysheva2 at 293.2 K, 296.2 K and 298.1 K by gas chromatography and presented in Fig. 26 at 296.2 K. Experimental errors were reported as ± 0.02 K.
         All experimental data are considered tentative.
