 Method/Apparatus/Procedure:
   Solubilities were calculated from partition coefficient measurements for the hydrocarbon between an aqueous solution and its vapor using headspace chromatography.
The apparatus and the method of obtaining the partition coefficients are described in detail in the paper. The hydrocarbon was introduced as a vapor (to avoid emulsification) into a glass equilibration cell containing about 45 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:
   (1) 99.99 mole percent purity;source and methods of purification not specified.
   (2) Prepared according to ref. 1. Purity not specified.

 Estimated Errors:
