Critical Evaluation:

            Quantitative solubility data for nitroethane (1) + 1-decanol (2) have been reported in the four publications listed in Table 1.

         The original data are compiled immediately following this Critical Evaluation. The data of Francis2 (nitroethane-rich phase only) are in marked disagreement with other studies and have been rejected. All other reported data are used in the Table 2 and Table 3
         Values obtained by the evaluator by graphical interpolation or extrapolation from the data sheets are presented in the Table 2 and Table 3. Data are "recommended" if two or more apparently reliable studies are is reasonable (± 5 % relative) agreement. All other data are regarded as tentative only.

         The upper critical solution temperature (UCST) has been reported as 291.6 K,2 294.2 K,3 and 294.4 K.4 The UCST of Francis2 is rejected. Thus, the recommended value are: Tc = (294.3 ± 0.1) K.
         The corresponding critical solution composition has been reported as xcl= 0.704, 2 xcl = 0.713,4 xcl = 0.716.3 The mean value xcl = 0.711 ± 0.005, is recommended.
         The recommended and tentative values for the mutual solubility reported in Table 2 and Table 3 have been approximated by an equation based on the scaling law (described in the preface to this volume) for which the following parameters were derived: a1 = 0.75504, a2 = 0.58994, b1 = 2.75647, b2 = -3.41196 (mean standard error of estimate was 0.0176).
         For this approximation, the recommended values of UCST and xcl were used. This relationship is presented in Fig. 10 together with experimental data reported in the four references.1-4
