Method/Apparatus/Procedure:
Water solubility was determined by the analytical method. Saturated mixtures were obtained by shaking of known volumes of reagents for 2-3 h after which the concentration of water in organic phase was determined by the Karl Fischer method. The mean of three analyses was reported. The saturation concentrations were reported in the units mole/L.
