The corresponding mass percent and mole fraction, x₁, calculated by compiler are 7.92 × 10^–5 g(1)/100 g sln and 1.25 × 10^–7.

Editor's Note: Based on the results for this and other hydrocarbon-water systems, uncertainty exists about whether the datum compiled here is independent of that of Price for the same system (see previous page). Consequently, this system has not been evaluated.

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   The saturated solutions of (1) in (2) were prepared in two ways. First, 200 mL of (1) was injected into 20 mL of (2) and thermostatted at 25°C. Second, the mixture of (1) and (2) as above was thermostatted at 70°C and then cooled to 25°C. The time required to obtain equilibrium was three weeks. The solubility of (1) in (2) was measured by glc. A Perkin-Elmer model F-11 gas chromatograph equipped with a 100-150 mesh Porasil column (70°C) and a flame ionization detector was used. Saturated solutions of heptane in (2) were used as standard solutions.

Source and Purity of Materials:
   (1) not specified.
   (2) not specified.

Estimated Errors:
   Solubility: 0.04 mg(1)/kg(2) (standard deviation from 7-9 determinations).
