Method/Apparatus/Procedure:
   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 cm3 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.

Source and Purity of Materials:
   (1) 99.99 mole per cent purity; source and methods of purification not specified.
   (2) Prepared according to ref. 1. Purity not specified.

Estimated Errors:
   Solubility: see table above
   Temperature: ± 0.01 K
