Method/Apparatus/Procedure:
Gas-liquid chromatography was used for the determination of the partition of trichloromethane with thin layers of water coated on Porasil D. Helium carrier gas was pre-saturated with water at the column temperature. The eluents were detected with an F. & M. flame ionization detector. The partition coefficient ($K_{\rm{L}}$) was calculated from the slope of the straight line plot of $V_{\rm{N}}/A_{\rm{L}}$ versus $V_{\rm{L}}/A_{\rm{L}}$.
