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 four days. Analyses were carried out by GSC 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:
- Phillips Petroleum Company; Chemical Samples Company or Aldrich Chemical Company; 99+%.
- Distilled.
Estimated Errors:
Ambient temperature: ±1°C
Mass concentration (m/v) (1): ±1.0 mg(1)/kg(2)
Components:
- 1,4-Dimethylbenzene, $\ce{ C8H10 }$; [106-42-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of p-Xylene in water at 25°C and at system pressure was reported to be 157.0 mg(1)/kg(2). The corresponding mass percent and mole fraction, x1, calculated by the compiler are 0.0157 g(1)/100 g sln and 2.66 × 10-5.
