Method/Apparatus/Procedure:
Saturated solutions of tritum labeled (2) in (1) were prepared in two ways. In the first, nitrogen was passed through the vessel with (1) and frozen. In the second, about 500 mL of (1) and 1 mL (2) were stirred. The concentration of (2) in (1) was calculated from scintillation measurements.
Source and Purity of Materials:
- source not specified; pure grade; shaken with conc. H2SO4; washed with water, dried over sodium, and distilled; purity not specified. B.p. 98.43°C, m.p. -90.8°C.
- source not specified; commercial; 1 Ci/mL HTO as received.
Estimated Errors:
Ambient temperature: not specified.
Experimental Values:
Note: The solubility of water in heptane at 23°C was reported to be 0.0139 g(2)/100 g sln.The corresponding mole fraction, x2, calculated by the compiler is 7.73 × 10-4.
