Glass Ball as Bullet Solubility System: 1,2,4-Trimethylbenzene with Artificial seawater

   (1) Artificial seawater (ref 1); ; []  NIST Chemistry WebBook for detail
   (2) 1,2,4-Trimethylbenzene; C9H12; [95-63-6]  NIST Chemistry WebBook for detail

Original Measurements:
   Sutton, C.; Calder, J.A., J. Chem. Eng. Data 1975, 20, 320-2.

   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

Experimental Remarks:

   The solubility of 1,2,4-trimethylbenzene in artificial seawater is reported to be 39.6 mg(1)/kg sln. The corresponding mass percent and mole fraction, x1, calculated by the compiler are 3.96 × 10–3 g(1)/100 g sln and 6.09 × 10–6 assuming the artificial seawater composition of ref 1.

Experimental Data:   (Notes on the Nomenclature)
   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: 0.5 (std. Dev.)
   Temperature: ± 0.1°C
