Glass Ball as Bullet Solubility System: sec-Butylbenzene with Artificial seawater
Components:
   (1) sec-Butylbenzene; C10H14; [135-98-8]  NIST Chemistry WebBook for detail
   (2) Artificial seawater (ref 1); ; []  NIST Chemistry WebBook for detail
Original Measurements:
   Sutton, C.; Calder, J.A., J. Chem. Eng. Data 1975, 20, 320-2.

 Variables:
   Temperature = 25.0 °C   
pH = One salinity: 34.5 g salts/kg sln
   Concentration = One salinity: 34.5 g salts/kg sln

 Prepared By:
   M. Kleinschmidt and W. Shiu

 Experimental Remarks:
   The solubility of sec-butylbenzene in artificial seawater is reported to be 11.9 mg(1)/kg sln. The corresponding mass percent and mole fraction, x1 calculated by the compiler are 1.19 × 10–3 g (1)/100 g sln and 1.64 × 10–6 assuming the artificial seawater composition of ref 1.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   A test tube containing (1) was placed in a flask containing (2) thus allowing for equilibration through the vapor phase. The saturated solution was extracted with hexane and analyzed by gas chromatography.

 Source and Purity of Materials:
   (1) from either Aldrich Chemical Co. or Matheson Coleman and Bell, 99+% pure.
   (2) made from doubly distilled water and salts 99+% pure.

 Estimated Errors:
   Solubility: 0.2 (std. dev.)
   Temperature: ± 0.1°C
