Method/Apparatus/Procedure:
In a 250 mL glass 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. In the case of shaking, the solution was allowed to stand for two days to permit separation of small (1) droplets. Absence of emulsion was checked microscopically. A 50 µL sample of the (1) saturated water was withdrawn with a Hamilton Syringe and injected into the fractionator of the gas chromatograph.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:
- Phillips Petroleum Co.; 99+% purity; used as received.
- Distilled.
Estimated Errors:
Ambient temperature: ±1.5°C
Mass concentration (m/v) (1): 0.008 mg(1)/kg sln (standard deviation from mean)

Experimental Data
The solubility of 2,2,5-trimethylhexane in water at 25°C was reported to be 1.15 mg (1)/kg sln.
The corresponding mole fraction, x1, calculated by the compiler, is 1.62 × 10-7.
The same value is also reported in ref 1.
