Method/Apparatus/Procedure:
Trichloromethane was equilibrated with water in an apparatus described elsewhere (ref. 1). The equilibration was allowed to take place for 2 days with the entire apparatus immersed in a water bath. The organic phase was analyzed for water by the Karl Fischer method (dead-stop end point). The microburet used for the titration was read to ± 0.01 cm

. All titrations were carried out in an atmosphere of dry nitrogen.
Source and Purity of Materials:
(1) Distilled.
(2) Source not given. Reagent grade, washed with distilled water and the purity was checked with GC.
