Method/Apparatus/Procedure:
Solubilities were calculated from partition coefficent measurements for the hydrocarbon and its vapor using headspace chromatography.
The apparatus and the method of obtaining the partition coeffients are described in detail in the paper. The hydrocarbon was introduced as a vapor (to avoid emulsification) into a glass equilibration cell containing about 43 cm3 of water. The vapor was subsequently analysed by gas chromatography using He as the carrier. Possible sources of error are discussed in detail although the source of vapor pressure data used to calculate solubilities are not given.
Source and Purity of Materials:
- 99.99 mole% purity; source and methods or purification not specified.
- distilled.
Estimated Errors:
Ambient temperature: ±0.01 K
Mass concentration (m/v) (1): See table above.
