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 A sample of the hydrocarbon-saturated water was withdrawn with a Hamilton syringe and gas liquid chromato-graphed in conjunction with a flame-ionization detector.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): 10 g(1)/106 g(2) (standard deviation of mean)
Components:
- 2-Methyl-1,3-butadiene, $\ce{ C5H8 }$; [78-79-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of 2-methyl-1, 3-butadiene in water at 25°C was reported to be 642 g(1)/106 g(2).
The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.0642 g(1)/100 g sln and 1.70 × 10-4.
