Experimental Remarks:

   The solubility of 2,2-dimethylbutane in water at 25 °C was reported to be 18.4 mg (1)/kg sln (0.00184 g(1)/100 g sln).
The corresponding mole fraction, x1, calculated by the compiler, is 3.85 x 10-6.
The same value is also reported in refs 1 and 2.

Experimental Data:   (Notes on the Nomenclature)
   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 A 50 microliter sample of the (1) saturated water was withdrawn with a Hamilton Syringe and injected into the fractionator of the gas chromatograph. A hydrogen-flame ionization detector was used. Many details are given in the paper.

Source and Purity of Materials:
   (1) Phillips Petroleum Co.; 99+% purity; used as received.
   (2) distilled.

Estimated Errors:
   Solubility: 1.3 mg (1)/kg sln (standard deviation of mean)
   Temperature: ± 1.5 K
