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
