The corresponding mass percent and mole fraction, x₁, calculated by compilers are 0.0165 g(1)/100 g sln and x₁ = 2.8 × 10^–5.

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   After an excess of (1) had been shaken with about 1 dm³ of (2) for about a week, a known volume of saturated solution was made slightly alkaline, and a stream of pure air passed through to drive off the (1). After passage through a silica tube packed with cupric oxide and heated to redness, the (2) was removed by concentrated sulfuric acid and calcium chloride and the carbon dioxide absorbed and weighed in soda-asbestos. The precautions usual in organic combustions were taken.

Source and Purity of Materials:
   (1) source not specified; purest obtainable material; distilled; purity not specified.
   (2) not specified.

Estimated Errors:
   Solubility: ± 1% (mean of large numbers of determinations)
