Quantitative solubility data for the system acetonitrile (1) and 1-decanol (2) have been reported in the publications listed in Table 1.
In addition to these data Schmid et al.5 determined of the upper critical temperature solution of components (1) and (2) in the course of a study of binary solubilities of acetonitrile and (C10-C20) alcohols. All original data are compiled in the data sheets immediately following this Critical Evaluation.
The upper critical solution temperature has been reported as 295.6 K,1 295.9 K,2 296.2 K,5 296.61 K,4 and 297.1 K,5 these data are in reasonable agreement and thus their average value: UCST = 296.3 ± 0.5 K and is recommended. The corresponding critical solution composition has been reported as xcl = 0.7563 and as xcl = 0.7674 and averaged value, xcl = 0.762 ± 0.005 is recommended.
Monotectic equilibrium has been reported to occur at 278.3 K.1
All experimental values reported1, 3,4 have been approximated by an equation based on the scaling law (described in the introduction to this volume) for which the following parameters have been derived:
a1 = 0.4740, a2= 1.8944, b1 = -3.8277, b2 = 0.6260
(mean standard error of estimate was 0.0269).
For approximation xcl and UCST from Szydlowski and Szykula4 have been used. In the opinion of the evaluators, the 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 experimental points1, 3,4 are also presented in Fig. 13.
