Glass Ball as Bullet Solubility System: Hexatriacontane with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Hexatriacontane; C36H74; [630-06-8]  NIST Chemistry WebBook for detail
Original Measurements:
   Baker, E.G., Am. Chem. Soc., Div. Petrol. Chem., Preprints 1958, 3, No. 4, C61-8.

 Variables:
   Temperature = 25 °C

 Prepared By:
   M.C. Haulait-Pirson

 Experimental Remarks:
   The solubility of hexatriacontane-18,19-C14 in water at 25°C was reported to be 1.7 × 10–9 g(1)/g(2).

The corresponding mass percent and mole fraction, x1, calculated by the compiler are 1.7 × 10–7 g(1)/100 g sln and 6.1 × 10–11.

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   Carbon-14 labeled (1) was used as tracer.
The technique of preparing a saturated aqueous solution of (1) by ultrafiltration of a (1)-(2) dispersion has been described in ref 1. A Packard Tri-Carb Liquid Scintillation Spectrometer was used to detect the radioactive (1) dissolved in (2).

 Source and Purity of Materials:
   (1) New England Nuclear Corporation; used as received.
   (2) Distilled.

 Estimated Errors:
   Solubility: 20% (standard deviation from 17 replicate runs).
