Quantitative solubility data for the system acetonitrile (1) and octane (2) have been reported in the publications listed in Table 1.
In addition to these data McLure et al.6 determined of the upper critical temperature solution and critical solution composition binary systems containing acetonitrile + alkanes (C5-C18). All original data are compiled in the data sheets immediately following this Critical Evaluation.
The upper critical solution temperature has been reported as 364.7 K,1 364.85 K,4 365.1 K,6 and 365.7 K.2 These data are in reasonable agreement and thus their mean value: UCST = 365.1 ± 0.3 K is recommended. The corresponding critical solution composition has been reported as xcl = 0.67.6
All experimental values reported3-6 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 = 0.9488, a2= -0.3334, b1 = 5.2227, b2 = -4.8685
(mean standard error of estimate was 0.0138).
For approximation xcl and UCST from McLure et al.6 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 selected temperatures are presented in Table 2. This relationship together with experimental points3-6 are also presented in Fig. 10.
