Experimental Remarks:

   The mutual solubility of nitroethane (1) and 1-decanol (2) in volume fractions is presented over the temperature range in graphical form.

Data extracted from the published graphs by the compilers. For conversions of volume concentration utilized values of density of nitroethane p(20 °C) = 1052.8 g·L^-1, Weissberger et al.¹ and 1-decanol p(20 °C) = 829.2 g·L^-1, Marsdne and Mann,² at 293.2 K (20.0 °C).
