Method/Apparatus/Procedure:
The synthetic (cloud point) method using sealed Pyrex tubes was employed. All values reported are an average of at least three determinations agreeing within 0.2 °C or better. No details were reported.
Source and Purity of Materials:
- Source not specified; spectroscopic grade; not purified.
- Prepared by the decarboxylation of perfluoro-n-octanoic acid; dried over phosphorus pentoxide and distilled on a ten plate microhelipod column at a reflux ratio of 5/1; BP = 95°C/100.1 kPa, $\rho^{25} = \pu{1718 g L-1}$.
Estimated Errors:
Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.

Experimental Data
The mutual solubility of acetonitrile and 1-hydropentadecafluoroheptane in volume fractions were reported over the temperature range in graphical form. Data presented here were extracted by the compilers from the reported graphs. Timmermans1 values of density acetonitrile ρ(25°C) = 776.8 g·L-1, was used in the above conversions.
