Method/Apparatus/Procedure:
The synthetic method was used. Water was introduced into a tube by condensation of known amount of vapor; the required amount of the octanol-benzene solution was siphoned into a tube which was then sealed.
Source and Purity of Materials:

(2) Source not specified; chemically purified, crystallized, distilled, dried over phosphoric anhydride.
(3) Source not specified.
Estimated Errors:
Solubility: Not reported.
Temperature: Composition <0.2%; temp. <0.2°C.
