Method/Apparatus/Procedure:
A combination of titration and analytical method was used. The apparatus and experimental procedure were described in [1]. For GLC analysis a 1.6 m column filled with Poropak-Q was used. Solubility of water in hexane was determined by the Karl Fischer method. Composition of the water-rich phase was determined by the gross composition of phase split liquid mixture and composition of the organic phase (concentration of hexane was assumed to be 0).
Source and Purity of Materials:
- Merck Uvasol, spectrograde; used as received; densities agreed within 0.0003 with literature values.
- Merck Uvasol, spectrograde; used as received; densities agreed within 0.0003 with literature values.
- De-ionized, twice distilled.
