Solubilities in the system comprising nitromethane and decanoic acid have been reported in two publications. Hoerr, et al.1 measured the mutual solubility of (1) and (2) between 285 and 328 K by the synthetic method. Schmid, et al.2 determined the upper critical solution temperature also using the synthetic method. At the UCST, the only temperature where direct comparison is possible, the two studies are in rather poor agreement: Hoerr et al.1 (328 K) and Schmid et al.2 (331.7 K). The UCST equal to 330.7 1 K calculated on the bases of relationship in the series nitromethane - acids (described in the Introduction material to this volume "Relations of Solubility Data in Binary Systems Containing Nitromethane") may be treated as tentative UCST of this system. However, it may be noted that the UCST values of Hoerr, et al.1 in well characterized nitromethane-acid systems are generally lower than other reports and thus the value from Schmid, et al.2 is probably more realistic. Nevertheless, in the absence of confirmatory studies, all data must be regarded as tentative.
The numerical solubility values are given in the following data sheet.
