Experimental Remarks:

   The solubility of 2-methylbutane in water at 25 °C and at system pressure was reported to be 48 mg(1)/kg (2). The corresponding mass percent and mole fraction,x1, calculated by the compiler are 0.0048 g(1)/100 g sln and 1.20 x 10-5.

Experimental Data:   (Notes on the Nomenclature)
   The solubility was determined at laboratory temperatures by use of screw-cap test tubes. The (1) phase floated on top of the water and insured saturation of the (2) phase in 2 to 4 days. Analyses were carried out by GLC using a Hewlett-Packard model 5751 gas chromatograph with dual flame ionization detectors. Many details are given in the paper.
