Method/Apparatus/Procedure:
The solubility of 1,1,1,2,2,3,3,4,5,5,5-un-deca-fluoro-4-(trifluoromethyl)-pentane in water was calculated from the kinetic data derived from observations of particle growth in aqueous emulsions in which Ostwald ripening takes place. The kinetics of the coarsening of particles was observed by photon correlation spectroscopy on a Coulter N4 instrument. The calculation was based upon the Lifshits-Slezov equation.
Source and Purity of Materials:
