Original Measurements:
Pavlov, S.Yu.; Serafimov, L.A.; Pavlova, S.P.; Kofman, L.S., Zh. Fiz. Khim. 40, 2719 (1966).
Variables:
Temperature = 275 K to 338 K
Prepared By:
Valerii P. Sazonov and Nikolai V. Sazonov
Experimental Remarks:
The mutual solubilities of acetonitrile (1) and 2-methylbutane (2) in mass percent over the specified temperature range were reported in graphical form in the original publication. Numerical data were extracted from the published graphs by the compilers. UCST was reported as 65.0 °C (338.2 K, compilers).
