Method/Apparatus/Procedure:
Experiments were performed in sealed stainless steel centrifuge tubes. An excess of styrene was added to a tube containing distilled water, and the tube was sealed and allowed to equilibrate at 25 ± 0.2 °C with constant or intermittent shaking. Equilibration was generally complete within one week. The mixture was then centrifuged at 10,000 rpm for 60 min in a head preequilibrated to 25 ± 0.3 °C, following which aliquots of the solution were removed for analysis by high-performance liquid chromatography using a Waters M6000A instrument fitted with a $\ce{C18}$ Bondapak column. The mobile phase was a mixture of methanol/water or acetonitrile/water. The entire procedure was carried out at least twice for each compound, and each analysis was also conducted in duplicate.
Source and Purity of Materials:
- Aldrich; purity not specified.
- distilled.
Estimated Errors:
Ambient temperature: ±0.2°C
Mass concentration (m/v) (1): ±5.7% rel. (representing one std. dev.)
Components:
- Styrene, $\ce{ C8H8 }$; [100-42-5] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of styrene in water was reported to be 1.54 × 10-3 mol/L sln. Assuming a solution density of 1.00 kg/L the corresponding mass per cent and mole fraction (x1) solubilities, calculated by the compiler, are 0.0160 g(1)/100 g sln and 2.77 × 10-5 respectively.
