Original Measurements

McAuliffe, C.; J. Phys. Chem. 1966, 70, 1267-1275.

Variables:

Room Temp: 25 °C

Prepared by:

Z. Maczynska, A. Maczynski, A. Szafranski

Method/Apparatus/Procedure:

In a 250-mL bottle, 10-20 mL of (1) was vigorously shaken for 1 hr, or magnetically stirred for one day, with 200 mL of (2) at 25 °C. The bottle was set aside for two days to allow droplets of undissolved (1) to separate. Absence of emulsion was checked microscopically. A sample of the hydrocarbon-saturated water was withdrawn with a Hamilton syringe and gas liquid chromatographed in conjuction with a flame-ionization detector.

Source and Purity of Materials:

1. Phillips Petroleum or Columbia Chemical; used as received.
2. Distilled.

Estimated Errors:

Ambient temperature: ±1.5°C
Mass concentration (m/v) (1): 5 g(1)/10⁶ g(2) (standard deviation of mean)
