Quantitative solubility data for the system of acetonitrile (1) + 2-methylbutane (2) have been reported in the publications listed in Table 1.
All original data are compiled in the data sheets immediately following this Critical Evaluation.
The upper critical solution temperature has been reported as 338.2 K.2 The corresponding critical solution composition has been calculated by evaluators as xcl = 0.50 from the data.2
All experimental values reported1-4 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 = 0.9283, a2= –0.2839, b1 = 0.7857, b2 = –0.7455
(mean standard error of estimate was 0.0191).
For approximation xcl and UCST determined by Pavlov et al.2 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 points reported1-4 are also presented in Fig. 5.
