Original Measurements
Natarajan, G. S.; Venkatachalam, K. A.; J. Chem. Eng. Data 1972, 17, 328-9.
Variables:
Room Temp: 25 °C
Prepared by:
M.C. Haulait-Pirson, G.T. Hefter
Method/Apparatus/Procedure:
15 mL of the aqueous medium was equilibrated with 1 mL of (1) by mechanical shaking in a thermostatted glass burette. After settling (judged visually), 5 mL of the aqueous layer was withdrawn and the olefin content determined by titration with bromine using standard procedures.
Source and Purity of Materials:
- Prepared by dehydration of 2-heptanol and then washed, dried, and fractionated. Purity (no specification) was determined by chromatography.
- Not specified.
Estimated Errors:
Ambient temperature: ±0.05 K
Mass concentration (m/v) (1): not specified.
Components:
- 2-Heptene, $\ce{ C7H14 }$; [592-77-8] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of 2-heptane in water was reported to be 2.716 × 10-4 mol L-1 at 25°C. a Assuming a solution density of 1.00 g mL-1 the corresponding mass percent and mole fraction (x1) solubilities, calculated by the compilers are respectively, 0.00266 g(1)/100 g sln and 4.89 × 10-6.
Solubility data are also presented as a function of temperature in various salt solutions.
