Critical Evaluation:

   Quantitative solubility data for the nitromethane + 1-decanol have been reported in the publications listed in Table 1.

Apart from the publication by Schmid et al.,2 which did not contain sufficient information to justify its inclusion, all the original data are given in the data sheets following this Critical Evaluation.

From the relationship of UCST in the nitromethane - alcohol series, discussed at the beginning of this volume in the Introduction material "Relations of Solubility Data in Binary Systems Containing Nitromethane," the nitromethane - 1-decanol UCST calculated value is 332.5 K. The most realistic experimental UCST = 332.9 K was measured by Sazonov4 - one of the evaluators of this system. The other experimentally measured UCST are: 329.5,1 330.2,2 330.7.3

The value of critical solution composition calculated from similar relationship of the nitromethane - alcohol series is 0.758, while the experimentally measured values are 0.753 (Ref. 1) and 0.760.4 These calculated values of UCST and critical solution composition, consistent in the series, may be treated as tentative. The solubility data reported in Refs 1, 2 and 3 have been rejected. Therefore only experimental data reported in Ref. 4 could have been approximated by the equation based on scaling law and discussed at the beginning of this volume. (For the consistent description all used values were those reported in Ref. 4.) The following parameters have been adjusted:

a1 = 0.84995, a2 = 0.03269, b1 = 8.37036, b2 = -7.84748

(mean standard error of estimate was 0.0195).

In the opinion of the evaluators, mutual solubilities calculated by this equation may be treated as tentative. The results of calculations for the selected temperatures are presented in Table 2. This relationship together with all experimental points1,3,4 is also presented in Fig. 29 .
