Original Measurements
McAuliffe, C.; J. Phys. Chem. 1966, 70, 1267-1275.
Variables:
Ambient temperature: One temperature: 25 °C
Prepared by:
Z. Maczynska, A. Maczynski, A. Szafranski
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. In the case of shaking, the solution was allowed to stand for 2 days to permit separation of small (1) droplets. Absence of emulsion was checked microscopically. A sample of the hydrocarbon-saturated water was withdrawn with a Hamilton syringe and gas liquid chromatographed in conjunction with a flame-ionization detector.
Source and Purity of Materials:
- Phillips Petroleum or Columbia Chemical; used as received.
- Distilled.
Estimated Errors:
Ambient temperature: ±1.5 K
Mass concentration (m/v) (1): 7 g(1)/106 g(2) (standard deviation of mean)
Experimental Values:
Note: The solubility of 1-pentene in water at 25°C was reported to be 148 g(1)/106 g(2).The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.0148 g(1)/100 g sln and 3.80 × 10-5.
