 Notes:
   a  Solubility values were calculated by the authors from their smoothed air-water partition coefficient (KAW) by assuming KAW values obtained at infinite dilution were valid at the saturatioin pressure of (1).

 Method/Apparatus/Procedure:
   Air-water partition coefficients were measured by saturating a portion of water by a stream of nitrogen containing a known vapour concentration of (1). After equilibration, the dissolved (1) was adsorbed in a porous polymer trap and the entrapped (1) analysed by gas chromatography. The method and apparatus are described in detail in ref 1.
