The solubility of 2,2-dichloro-1,1,1-trifluoroethane (1) in water (2) and that of water (2) in 2,2-dichloro-1,1,1-trifluoroethane (1) have been studied by two research groups. Details are not available on the experimental methods, apparatus, and procedures for the measurements. The binary system is treated in two parts; part 1 is 2,2-dichloro-1,1,1-trifluoroethane (1) in water (2) and part 2 is water (2) in 2,2-dichloro-1,1,1-trifluoroethane (1).
Part 1. The solubility of 2,2-dichloro-1,1,1-trifluoroethane (1) in water (2) has been reported in a du Pont bulletin¹ and by Sukornick² at 298.15 K only. There is a serious discrepancy between the two values and in the absence of other independent studies; it is not possible to determine which value is more reliable. Further studies will be necessary before even tentative values can be chosen. Part 2. Uncertainties regarding the solubility of water (2) in 2,2-dichloro-1,1,1-trifluoroethane (1) are similar to those concluded for the reciprocal system as drawn from the available solubility data. All the available solubility data are summarized in Table 1:
