Original Measurements:
McAuliffe, C., J. Phys. Chem. 1966, 70, 1267-75.
Variables:
Temperature = 25 °C
Prepared By:
A. Maczynski, Z. Maczynska, and A. Szafranski
Experimental Remarks:
The solubility of 2-heptane in water at 25°C was reported to be 15 g(1)/10
6
g(2).
The corresponding mass percent and mole fraction,
x
1
, calculated by the compilers are 0.0015 g(1)/100 g sln and 2.7 x 10
-6
.
Experimental Data:
(Notes on the Nomenclature)
Method/Apparatus/Procedure:
In a 250 mL glass bottle, 10-20 mL of (1) was vigorously shaken for 1 hr or magnetically stirred for 1 day, with 200 mL of (2) at 25 °C. Absence of emulsion was checked microscopically. A sample of the hydrocarbon-saturated water was withdrawn with a Hamilton Syringe and gas liquid chromatograph in conjunction with a flame ionization detector.
Source and Purity of Materials:
(1) Phillips Petroleum or Columbia Chemical; used as received.
(2) distilled.
Estimated Errors:
Solubility: 1.4 g (1)/10
6
g(2) (standard deviation of mean)
Temperature: ± 1.5 K
