Method/Apparatus/Procedure:
Tritio-octadecane was used as radioactive tracer. 0.01 of active (1) was shaken with (2); the mixture was filtered through a 0.05 µm filter; 0.01 mL of filtrate was vaporized in hot oxygen and passed over $\ce{CuO}$ at 600 °C; the $\ce{H2O}$-$\ce{T2O}$ derived from the vaporized solvent as well as from the combusted (1) was trapped at -78 °C; the melted ice was reduced by Zn and the gas was counted. Many details are given in the paper.
Source and Purity of Materials:
- Tritio-octadecane prepared by hydrogenating octadecene-1 with tritium; 100 curies of tritium were introduced per mole of (1).
- distilled.
Estimated Errors:
Ambient temperature: Not specified.
Components:
- Octadecane, $\ce{ C18H38 }$; [593-45-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The authors reported that the solubility of ocatadecane in water increases from about 55ppb by weight at room temperature to twice this amount at 80°C. A graph reporting the mole fraction x1 a function of the reciprocal absolute temperature is given.
