   (2) 1,2,4,5-Tetramethylbenzene; C10H14; [95-93-2]  NIST Chemistry WebBook for detail
Original Measurements:
   Price, L.C., Am. Assoc. Petrol. Geol. Bull. 1976, 60, 213-44.

 Variables:
   Temperature = 25 °C

 Prepared By:
   M.C. Haulait-Pirson

 Experimental Remarks:
   The solubility of 1,2,4,5-tetramethylbenzene in water at 25°C and at system pressure was reported to be 3.48 mg(1)/kg(2). The corresponding mass per cent and mole fraction, x1, calculated by the compiler are 3.48 × 10–4 g(1)/100 g sln and 4.67 × 10–7.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   The solubility was determined at laboratory temperatures by use of screw-cap test tubes. The (1) phase floated on top of the water and insured saturation of the (2) phase in 2 to 4 days. Analyses were carried out using a Hewlett-Packard model 5751 gas chromatograph with dual-flame ionization detectors. Many details are given in the paper.

 Source and Purity of Materials:
   (1) Phillips Petroleum Company; Chemical Samples Company or Aldrich Chemical Company; 99+%.
   (2) distilled.

 Estimated Errors:
   Solubility: ± 0.28 mg(1)/kg(2)
   Temperature: ± 1°C
