Solubility System: Acetonitrile with 1-Decanol

Components:
   (1) 1-Decanol; C10H22O; [112-30-1]  NIST Chemistry WebBook for detail
   (2) Acetonitrile; C2H3N; [75-05-8]  NIST Chemistry WebBook for detail

Original Measurements:
   Majgler-Baranowska, H.; Pyzuk, W.; Jeute, W.; Ziolo, J., J. Chem. Eng. Data 26, 51 (1981).

Variables:
   Temperature = 290 K to 297 K

Prepared By:
   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.
