SDS Volume (1099)
Volume 38. Hydrocarbons in Water and Seawater, Part II, p None
Original Measurements
Natarajan, G. S.; Venkatachalam, K. A.; J. Chem. Eng. Data 1972, 17, 328-9.
Variables:
Room Temp: 15 - 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 After settling (judged visually), 5 mL of the aqueous layer was withdrawn and the olefin content determined by titration with bromine using standard procedures.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-octanol 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): see above table.
Components:
- 2-Octene, $\ce{ C8H16 }$; [111-67-1] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
Compiler's note: Although the data have not been measured in pure water the low concentration of the added acid is unlikely to cause olefin solubility to differ markedly from that in pure water. Further solubility data are given in the paper for 0.05 and 0.1 mol L-1 HC1.
