Method/Apparatus/Procedure:
The apparatus described in [1] was used without modification. Samples were equilibrated in a constant-temperature water-bath maintained at 25 ± 0.1 °C. Water solubilities were determined by using a Beckman Model KF-3 Aquameter.
Source and Purity of Materials:
- source not specified; certified or reagent grade; distilled through a 30-plate Oldershaw column.
- not specified.
Estimated Errors:
Ambient temperature: ±0.1 K
Mass concentration (m/v) (1): ±0.0005 mol(2) dm-3 sln (type of error not specified)

Experimental Data
The solubility of water in toluene at 25°C was reported tobe 0.0274 mol (2) dm-3 sln.
the corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.0572 g(2)/100 g sln and 2.92 × 10-3. The assumption that 1 dm3 sln = 862 g sln was used in the calculation.
