Conditions:

Room Temp: 0 - 20 °C
Salinity: 34.42 g salts/kg sln

Compilers:

G.T. Hefter, D.G. Shaw

Methodology:

Solubilities were calculated from partition coefficent measurements for the hydrocarbon between an aqueous solution and its vapor using chromatography.
The apparatus and the method of obtaining the partition coefficents are described in detail in the paper. The hydrocarbon was introduced as a vapor (to avoid emulsification) into a glass equilibrium cell containing about 45 mL of water. The vapor was subsequently analyzed 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.
