Methodology:
A method of gravimetric absorption monitored by tritium tracer was used. (1) was equilibrated with a slight excess of titrated water by shaking over a period of at least 8 hr in a thermostat. The phases were allowed to separate for at least 16 hr and then were sampled for tritium analysis. Most of the (1) phase was weighed into a boiling flask of a closed distillation system and then distilled through a magnesium perchlorate weighing tube. The magnesium perchlorate was then dissolved for measurement of its tritium content by liquid scintillation counting with a Packard Tri-Carb Scintillation Spectrometer.
Sample Information:
- source not specified; spectralgrade reagent.
- tritiated water at 5 Ci/mL; New England Nuclear Corp.; diluted to about 1 mCi/mL.
Measurement Errors:
Mass concentration (m/v) (1): better than 1% (type of error not specified)

Experimental Data
The solubility of water in cyclohexane at 25°C was reported to be 0.00345 mol(2) dm×3 sln corresponding to a mole fraction, x2, of 3.75 × 10-4. The corresponding mass percent value calculated by the compiler is 0.0080 g(2)/100 g sln.
The compiler's calculation assumes a solution density of 0.7739 g mL-1 (density of cycolhexane reported in ref 1).
