   Valerii P. Sazonov and Nikolai V. Sazonov

Experimental Remarks:

   The mutual solubility of acetonitrile (1) and 1-decanol (2) in volume fractions was reported over the temperature range in graphical form. Data were extracted from the published graphs by the compilers. Timmermans1 values of the density of acetonitrile ρ(20 °C) = 782.2 g·L-1 and Marsden and Mann2 value for 1-decanol ρ(20 °C) = 829.2 g·L-1 at 293.2 K (20.0 °C) were used for conversions.
