Method/Apparatus/Procedure:
The saturation of 1,1,2-trichloro-1,2,2-tri-fluoroethane in aqueous salt solution was performed in a steel vessel during 10 hours. The mixture was stirred and left to stand for 7 hours before the gas chromatographic analysis. The chromatograph was equipped with an electron capture detector. The determination of the solubility at a given condition was repeated five to six times. Further details are available.
